Why compress ppt files.

PPT also goes by the name of PowerPoint Presentation and are used in all walks of life including the home, school and at work. PPT files can range in size depending on the content of the presentation. If a presentation contains a lot of images or videos then the file size can be especially large. Even just one high resolution image - such as a BMP - can increase the size of a PPT file tenfold. When a user complains that they have run out of space in their mailbox it is typically because they've been sent one too many large presentations. It is not surprising then that there is such a need to compress PPT files so that they do not take up as much storage and can be more easily shared. Using the Zamzar PPT compression tool, individual (and sizeable) elements - such as pictures and videos - are compressed bringing the overall file size down. Once compressed, the PPT (including the images and video within it) does not suffer from any noticeable loss in quality despite the file size being shrunk. It's worth remembering that if you receive a PPT file and need to send it on you can always put it through the Zamzar compression tool before you do so.

Any Operating System

It doesn’t matter what operating system you’re running; as long as you have a web browser, Zamzar can convert your files.

Zamzar prides itself on the highest-quality file conversion, so you won’t be able to tell the difference between your uploaded file and your newly converted file.

Learn how to reduce the size of your PPT files significantly, at no cost, using Smallpdf. No watermark, no registration, and no installation.

We’ve come across many large PPT files in our years of compressing digital documents, from sales pitches to lecture material and business proposals. Usually, the need to reduce the size of these files comes from having to share them via email, where the file size cap is around 20 MB. Compressing PowerPoint files also comes in handy to save storage space, be it on your local computer or an otherwise pricey cloud service such as Dropbox. You can use our online compress tool to shrink your PPT down significantly and thus make your life easier and save some money.

Will the Document’s Formatting Remain the Same?

We aim to maintain the layout and quality of your document as close to the original PPT as possible. We actually first turn your PowerPoint into a PDF document; then, our compressor looks for repeating patterns in the data and replaces them with unique identifiers. This is actually what makes your file smaller. This process doesn’t touch attributes like fonts and the layout of your PPT, so they should stay just as they are.

Smallpdf caters to millions of users every month and uses the most reliable software on the internet to convert, edit, and compress files. So, you can trust that we’ll produce only the absolute best conversion quality.

There are extra measures that you can take to be absolutely sure that the final content resembles its original form. You can “embed” the fonts of the text in your PowerPoint presentation. You’ll find this option under “Preferences” in PowerPoint. Doing this will ensure that the fonts remain the same, even when we don’t have the same ones on our servers.

PowerPoint compressor features

How can i reduce the file size of a powerpoint file.

If you need to compress a PowerPoint presentation , you should always start with the native compression features in PowerPoint.

They can help you cropped areas of pictures and reduce the resolution of photos without affecting presentability.

If you need to further reduce the size of your PowerPoint, you can try things like compressing the file in a .zip folder, compressing the file as a PDF, or using an online PowerPoint compressor.

Why is my PowerPoint file so large?

The primary reason that PowerPoint files become very large is because of media - images, video, and audio.

You can have dozens or hundreds of text slides, and still maintain a small file size, but just one or two large images can drastically increase the file size of your PPT file.

If you would like to nerd out and see what is driving the size of your PowerPoint file, you can convert it to a .zip folder by renaming the file extension from .pptx to .zip, and then open up the .zip to see the sizes of the individual items within the file.

How do I send a large PowerPoint file?

To send a PowerPoint as an email attachment, you should try to keep it (or compress it to) under 20MB. The limit can be higher for certain email providers, but this will help to maximize your deliverability.

If you file is larger than 20-25MB, you should use a cloud file-sharing platform like OneDrive or Google Drive and send your recipient a link to download the presentation, rather than using an attachment.

Why is my PowerPoint so slow?

When PowerPoint files become very large, they can noticeably slow down your PowerPoint app and make it difficult to work.

In these cases, you may want to reduce the file size of your presentation to ensure you can work efficiently, and the app does not crash.

How do I create a PowerPoint with AI?

Creating a PowerPoint with AI is easy! You can use tools like Plus AI and Copilot to create a presentation from a prompt or an existing source document like a PDF or a Word doc.

Check out our list of the Best AI Presentation Makers to see what's out there, and the latest capabilities of these types of tools.

Will zipping a .PPTX file reduce its file size?

Interestingly, a .pptx file is actually already a zip folder with the contents of a presentation. If you change the file name of your .pptx file to .zip, you can open it like a normal .zip folder and view the contents of your presentation.

Nevertheless, it seems like "rezipping" the already compressed files can reduce the size of your .pptx document.

How to I reduce the file size of a PPT as a PDF?

Sometimes you can reduce the file size of a PowerPoint presentation by exporting it as a PDF document.

When going through this process, you can change the desired quality of the PDF document, and selecting a lower quality will reduce the size of the PPT file.

You may also notice differences between the size of the PDF file from a PPT export when using Windows or Mac because they use different PDF utilities, so that is another way to experiment with reducing the file size of your PDF.

Can I reduce the file size of a PDF file?

PDF files can sometimes be larger than the original document, and if you are trying to send a presentation as a PDF attachment in an email, that might be a problem.

To reduce the size of your PDF, try opening the PDF in Adobe Acrobat and using the "Reduce file size" feature.

Compress PowerPoint to reduce the file size

02.12.20   •  #powerpointtips.

Sometimes, the file size of your PowerPoint presentation can get very big. In some cases, that can be annoying, e.g. when trying to send the slides via email, but not being able to do so because the file is too large. Usually, pictures and videos are the reason why presentations become too big. The good news are that you can easily compress pictures and embedded media files by following the steps listed below.

Compress images

Compress videos and audios.

• Convert PPT into a PDF file
• Get rid of 3D-models

Compress PPT as ZIP- file

PowerPoint offers the option to compress all images at once or choose single pictures to reduce their file size. Keep in mind, that compressing an image will automatically reduce its quality as well. If you don't need to reduce the file size, better use the highest quality resolution as possible.

There are two ways to compress images within your PPT file which nearly work the same way:

Compress selected pictures

• Select the image you want to compress or any picture if you wish to reduce the size of all graphics
• Navigate to the Picture Tools Format tab and select Compress Pictures

• A new menu pops up. Choose your compression options and make sure to check "Delete cropped areas of pictures" and uncheck "Apply only to this picture" (if you want to compress all images)
• High fidelity: preserves quality of the original picture
• HD (330 ppi): good quality for high-definition (HD) displays
• Print (220 ppi): excellent quality on most printers and screens
• Web (150 ppi): good for web pages and projectors
• E-mail (96 ppi): minimize document size for sharing
• Use default resolution

Compress all images while saving the PPT file

• Open your presentation. Go to File in the PowerPoint menu
• Click Save as and then Browse
• In the window that opens, click on Tools (right beside Save )
• Select Compress Pictures and choose the resolution you need To save even more space, you can additionally choose Delete cropped areas of pictures to remove the parts of pictures which you cropped in PowerPoint.
• Click OK and then Save

Video and audio files can increase your PPT size a lot. It's a good idea to compress those if you want to make some space. Some PowerPoint versions make it possible to decrease the media size in PPT but if this option is missing in your program, online video compressors are the solution.

Compress videos and audios in PPT

• Go to File in the PowerPoint menu
• Open the Compress media drop down
• Choose a compression file size. Don't reduce the quality too much and check if the appearance of your media doesn't look too grainy on the actual projector you will be presenting on

Online video compressor

There are plenty of online video compressors which you can use to reduce the video size in advance. For example, the website FreeConvert makes it easy to decrease the file size without having to download anything. This way you can integrate a smaller media file into PPT.

Links instead of videos

Instead of importing a video to your PPT slides, including a link to your PowerPoint presentation can save a lot of space. If your video is somewhere on YouTube or other online video-sharing platforms, include a link and use it when you're presenting. But notice: a link can only be used, if you're connected with wifi. Watching videos online, can take time and a bad connection might give you some unwanted breaks during your presentation. In this case, saving the video on your disk and opening it separately can save time and still reduce the size of the PPT.

Convert PPT to PDF

By converting a PowerPoint file into a PDF, the size will reduce automatically. During the process, images get compressed and some media (audio, videos, 3D models..) get removed. If you want to change the PowerPoint slides at all time, this method might not be the right one for you, as PDF files can't get edited the way a PowerPoint can. Hence, converting PPT into PDF only makes sense if your presentation will work as a handout and if the PDF files options are enough for you.

• Click Export
• Hit the Create PDF/XPS button
• Choose a location in which you want to save your PDF file
• Click Publish

Get rid of 3D models

The Office 365 subscription makes it possible to add 3D models to your PowerPoint slides. Nevertheless, those media require much space since they transport a lot of information. In order to minimize the PPT file, exchanging the 3D model with a normal image will easily reduce the size of your PowerPoint file.

If you need to share your PPT with someone, a ZIP- file format might help you to reduce the size of the PowerPoint. Even though, this method can save some place temporally, it might not be enough to send it via email. Uploading it to file-sharing platforms, such as GoogleDrive, DropBox, OneDrive or other websites and sharing its link to download the PPT, can be the better option. (Using an USB for sharing the presentation without the need to decompress anything would be the best solution)

Here's how to convert a PPT into a ZIP- file format:

• Select the file you want to minimize in the File Explorer
• Right-Click the file and hit Send to
• Choose the Compressed (zipped) folder option

If you want to decompress a ZIP- file into its original PowerPoint format:

• Right-Click on your ZIP- folder
• Select Extract All... or the similar operation of your program
• Choose a File Location to extract your file to, or extract it at the place you are currently at

How can I reduce the size of a PowerPoint file?

There are several ways to reduce the file size of a PowerPoint. You can compress images, videos and audios, convert your presentation into a PDF file, get rid of 3D models or compress the PowerPoint as a ZIP-file. We explained for you how all of this works in our blog.

How do I compress a video in PowerPoint?

To compress videos in PowerPoint, go to "File" in the PowerPoint menu and then click on "Info". Then open the drop-down menu "Compress media" and select the size of the compression file. Be careful not to reduce the quality too much and check that the quality of your video on the projector you will be presenting on is not too bad.

The big change in PowerPoint 2007 was that the stable binary file format of 97-2003 (.ppt files) was replaced as the default by a new zipped XML-based Office Open XML format (.pptx files). Microsoft's explanation of the benefits of the change included: smaller file sizes, up to 75% smaller than comparable binary documents; security, through being able to identify and exclude executable macros and personal data; less chance to be corrupted than binary formats; and easier interoperability for exchanging data among Microsoft and other business applications, all while maintaining backward compatibility.

Compress PowerPoint Presentations Without Quality Loss

Reduce the file size of your PowerPoint presentations

If the file size of your presentation is too large, try the following tips to make it more manageable.

Compress pictures in your presentation

Select a picture in your document. The Picture Format tab appears.

On the Picture Format tab, in the Adjust group, select Compress Pictures .

Under Compression options , do any of the following:

Make sure that Apply only to this picture is not selected so that the changes you make here will apply to all pictures in the document.

Select Delete cropped areas of pictures . This option removes the cropped picture data but note that if you delete the cropped picture data, you won't be able to restore it.

Under Resolution , select Use default resolution .

Under Compression options , do either of the following:

Select Delete cropped areas of pictures . This option removes the cropped picture data but note that if you delete the cropped picture data, you won't be able to restore it.

Delete image editing data and lower default resolution

By default, when you edit an image, the data from the original is retained (to ensure the image can be restored). Discarding it means that you can't restore the changes you make, but it will reduce your file size. Lowering the default resolution for images also reduces your overall file size.

Go to File > Options > Advanced .

Under Image Size and Quality , do the following:

Select Discard editing data . This option removes stored data that's used to restore the image to its original state after it's been edited. Note that if you discard editing data, you won't be able to restore the image after you edit it.

Make sure that Do not compress images in file is not selected.

Reduce the character set of embedded fonts

To make your presentation more sharable with others who don't have the same fonts in their system, it's typical to embed the fonts you use. However, embedded fonts will increase your file size. To minimize the file increase, embed only those characters used in the presentation.

Go to File > Options > Save .

Note:  If you've used custom fonts and want others to edit the presentation, select Embed all characters .

Reduce the file size of your Excel spreadsheets

Reduce the file size of your Word documents

How to compress ppt files.

First, you need to select an application from the available options and upload the PPT/PPTX file

Compress it

In the next step, you need to select the necessary settings and proceed to compress your image.

And finally, when everything is ready, you can download the file to your device and check it.

What is PPT

Microsoft Office PowerPoint (or simply PowerPoint) is the name of a special program designed to create and deliver presentations. PowerPoint was developed by Microsoft and since 1990 has been an integral part of the Microsoft Office suite. PowerPoint was originally developed for Macintosh computers, but later expanded to be used on the Microsoft Windows operating system. To share your presentation, you can record it in video format. This allows you to send it by e-mail, publish it on the Internet or save it to disk. When converting your presentation to a movie, you can add voice-overs, set the timing of the slide show, and even record your pointer movements. You can watch a presentation in this format without PowerPoint; it will play as a video file.

How PPT compression works

Information in PowerPoint is placed on separate sheets - slides. Each slide can have its own design and size. Information on a slide can be presented in the form of text, images, photos, videos. Each block of information on a slide can be animated. You can also apply animation effects to transitions between individual slides. If you paste pictures into slides using the clipboard (copy-paste), then you are doing it wrong. Use the standard image insertion function. Often, when using the insert method by CTRL + C / CTRL + V, the JPEG image is automatically converted to PNG or BMP format, which is much heavier in itself. Before embedding any image in your presentation, make sure that it does not need editing. Otherwise, first use any third-party editor (Photoshop, Gimp, Paint, etc.) to make edits and only then paste the final version.

10 Ways to Compress PowerPoint Presentations to Reduce File Size

10 Strategies to Compress or Reduce the Size of Large PowerPoint Presentations

by Avantix Learning Team | Updated September 21, 2023

Applies to: Microsoft ®  PowerPoint ® 2013, 2016, 2019 and 365 (Windows)

You can compress or reduce the size of large PowerPoint presentations in several ways. The most common strategy to reduce the size of a PowerPoint file is to compress pictures, video and audio. However, you can also use other methods to make files smaller including saving media and PowerPoint files in other formats and converting or removing embedded objects.

In this article, we'll look at 10 ways to compress or reduce the size of a PowerPoint presentation:

• Compress pictures
• Insert pictures instead of copying and pasting
• Use smaller image files
• Convert images to a different file type
• Save a copy of images with artistic effects
• Compress audio and video
• Link to audio or video files
• Convert Excel charts and other embedded objects
• Save a copy of large PowerPoint files
• Save a copy in PDF format

Note: Buttons and Ribbon tabs may display in a different way (with or without text) depending on your version of PowerPoint, the size of your screen and your Control Panel settings. For PowerPoint 365 users, Ribbon tabs may appear with different names. For example, the Picture Tools Format tab may appear as Picture Format.

To view file size in PowerPoint:

• Click the File tab in the Ribbon.
• Click Info. In the Properties area, file size is listed beside Size.

Once you've completed the following strategies, close and save the PowerPoint file, reopen it and check the file size again. You can also view file size in Windows 10 File Explorer or Windows Explorer in older versions of Windows.

1. Compress pictures

One of the most common ways to reduce file size is to compress one or all of the pictures in your PowerPoint file. You may want to try this with one picture at a time to be sure you are satisfied with the result after compression.

To compress a picture:

• In Normal View, select a picture on image on a slide.
• Click the Picture Tools Format or Format Picture tab in the Ribbon.
• In the Adjust group, click Compress Pictures. A dialog box appears.
• Select the check box to Apply only to this picture if you want to compress only the current picture or uncheck this option if you wish to compress all pictures in the presentation.
• Select the check box to Delete cropped areas of pictures if you have cropped images and want to permanently delete the areas you have removed by cropping.
• Choose the desired document resolution.

Don't forget to check pictures in Slide Master View (click the View tab in the Ribbon and then click Slide Master) as you may want to compress or delete those images as well.

Also, be sure to check image(s) after you compress them to be sure to are satisfied with the quality of the image(s). If you create a copy of the presentation before compressing the image(s), you can revert to the original if necessary.

2. Insert pictures instead of copying and pasting

It's best to insert pictures, rather than copying and pasting (or dragging and dropping) into the PowerPoint file. When you copy and paste (or drag and drop) an image into a presentation, it can lose compression, change file type and also bring in other data that can increase file size.

To insert a picture onto a PowerPoint slide:

• In Normal View, display the slide where you want to insert a picture.
• Click the Insert tab in the Ribbon and click Pictures (2013 and later versions) or Picture (2010). You can also click the Pictures or Picture icon in a placeholder on a slide. A dialog box appears.
• Navigate to the location of the picture.
• Select the picture and click Insert or double-click the picture.

You also have the option of linking to a picture file by clicking the arrow beside Insert in the Insert Picture dialog box and then choosing Link to File. However, the picture is not actually "in" the file (which reduces file size) and if you email the document, the pictures will not be included. If you use this strategy, it's best to copy the picture to the same folder as the PowerPoint presentation and be sure to bring the entire folder with you when you deliver the presentation.

3. Use smaller image files

It's best to insert pictures in smaller sizes to reduce the size of your PowerPoint files. For example, if you are inserting pictures from a phone taken at a high resolution, this will result in larger PowerPoint decks. Create, save or send images at a lower resolution and insert the lower resolution images into your PowerPoint files.

If you're using stock images, select images at the lowest resolution (at the quality level you require). You can also open an image in an image editing program (such as Microsoft Picture Manager or Adobe Photoshop) and then save it at a lower resolution.

In PowerPoint 365, one of the biggest culprits causing inflated file size is 3D models. Although 3D models are not inserted as pictures but rather as 3D models, they are images. One 3D model we inserted took up 17 MB of space. You can't compress 3D models like other types of images so you may need to delete 3D models or use a picture instead of a 3D model if file size is an issue.

4. Convert images to a different file type

Prior to inserting an image in PowerPoint, you can open it in an image editing program (such as Microsoft Picture Manager or Adobe Photoshop) and then use Save As to save the image in another format.

The format that will result in the smallest size is usually JPEG (Joint Photographic Experts Group format) or JPG. The JPEG compression algorithm significantly reduces the file size of images.

You can also save images in PowerPoint in different formats:

• Right-click the picture. A drop-down menu appears.
• Select Save As Picture. A dialog box appears.
• Navigate to the folder where you want to save the image.
• Enter a name for the file and select a format such as JPG or PNG.
• Click Save.
• In the PowerPoint presentation, delete the original image.
• Click Insert and then click Picture(s).
• Navigate to the location with the image you saved.
• Double-click the image.

5. Save a copy of images with artistic effects

When you apply an artistic effect to an image, PowerPoint retains two copies of the image (the original and a copy with the artistic effects). This allows the user to reset the image but can significantly increase file size. Compressing pictures also doesn't normally have any effect on images where you have applied artistic effects.

If you have applied an artistic effect (such as blur) to an image, you can reduce file size using the following method:

• Right-click the image with the artistic effect. A drop-down menu appears.
• Enter a name and select a file type (usually JPG or PNG).
• In the PowerPoint presentation, delete the image with the artistic effect.
• Navigate to the location with the image you saved with the artistic effect.

6. Compress audio and video

In 2010 and later versions of PowerPoint, audio and video files are copied into presentations rather than linked to the original files. You can improve playback performance and reduce PowerPoint file size by compressing audio and video files in your presentation.

Files can be compressed at different quality levels.

In PowerPoint 2013 and 2016, you can compress to the following quality levels:

• Presentation Quality – select this option to save space but maintain overall audio and video quality.
• Internet Quality – select this option and quality will be comparable to media which is streamed over the web.
• Low Quality – select this option if space is limited, such as when you are sending presentations via e-mail.

In PowerPoint 2019 and 365, you can compress to the following quality levels:

• Full HD (1080p) – select this option to save space while maintaining overall audio and video quality.
• HD (720p) – select this option to save space and the quality will be comparable to media which is streamed over the Internet.
• Standard (480p) – select this option when space is limited, such as when you are sending presentations via e-mail.

The following compression options appear in PowerPoint 2019 or 365:

Note: Some older video file formats may not compress or export properly. Embedded subtitles and alternate audio tracks will be lost in the compression process.

To compress media in PowerPoint:

• Open the presentation that contains the audio or video files you want to compress.
• Save a copy of the presentation so you can retain a copy of the file with the original media.
• In the copy, click the File tab in the Ribbon.
• Click Info.
• In the Media Size and Performance area, click Compress Media. A dialog box appears.
• Select the desired compression option. A dialog box appears indicating that media compression is in progress. PowerPoint will indicate how much space is saved.
• When compression is complete, click Close.

7. Link to audio or video files

You also have the option of linking to audio or video files. When you insert an audio or video file, click the arrow beside Insert in the Insert dialog box and then choose Link to File. Linked audio or video is not actually "in" the presentation (which reduces file size) and if you email the presentation, the media files will not be included if you have linked to audio or video files. Linking was the default behavior in PowerPoint 2007 and earlier versions for video and larger audio files.

If you choose to link to audio or video files, t's best to copy the media files to the same folder as the PowerPoint presentation and be sure to bring the entire folder with you when you deliver the presentation.

Note: You cannot apply certain types of formatting to linked video files.

8. Convert Excel charts and other embedded objects

Embedded objects such as Excel charts or worksheets can also increase file size. If you convert embedded objects to images, it can impact the size or your presentation. You can also reduce file size by breaking links to Excel files.

If you want to convert embedded objects into pictures, you can ungroup them or cut and paste them back into PowerPoint.

To ungroup an object:

• Select the chart or embedded object.
• Click the Format tab in the Ribbon. This tab may appear as Drawing Tools Format, Drawing Format or Shape Format.
• Select Group and then Ungroup. A dialog box appears asking if you want to convert the object to a PowerPoint object.

To cut an object and paste it back into a presentation as a picture:

• Select the embedded chart or object.
• Press Ctrl + X to cut it.
• Click the Home tab in the Ribbon.
• Click the arrow below Paste to display the drop-down menu and then choose Paste Special.
• Select an image type (such as JPEG) and click OK.

If you have links to Excel files, you can reduce file size using Edit Links to Files. Check out How to Break, Update or Change Links to Excel Charts or Worksheets in PowerPoint for more information on how to break links.

9. Save a copy of large PowerPoint files

It's a good idea to save a copy of a large PowerPoint files periodically using Save As and give the file a different name (i.e. Sales Presentation and the date). If you save a copy using Save As, version history and some editing data is removed during the process and this will reduce file size. This can also help avoid corrupted files.

To save a copy of a PowerPoint presentation:

• Choose Save As. If necessary, click Options or More Options. A dialog box appears.
• Navigate to the desired location.
• Enter a new name for the presentation.

10. Save a copy in PDF format

It's also common to save a copy of a presentation as a PDF (portable document format) file to reduce the size and then share it with others. You can compress images during the process.

To save a PowerPoint presentation as a PDF (and compress images):

• Choose Save As and then click Options or More Options if necessary. A dialog box appears.
• Navigate to the desired location and enter a name for the file. You can use the same name since the extension will be different (PDF).
• Under File Type, select PDF.
• Click Tools on the bottom right of the dialog box. A drop-down menu appears.
• Select Compress Pictures. A dialog box appears.
• Click the desired compression option.

Large file size is a common problem in PowerPoint and you can use these strategies to reduce the size of your PowerPoint presentations. Compressing the size of your decks should also help to improve speed and avoid crashes.

How to Fade a Picture or Part of a Picture in PowerPoint (Using a Gradient)

You can fade a picture in PowerPoint by drawing a rectangle shape on top of the picture and then filling the rectangle with a gradient from opaque to transparent. This technique is often used to fade an image into the background of a slide. Since the rectangle is placed on top of the image and then text may be placed on top of the rectangle, you may need to reorder the objects.

How to Lock an Image, Shape or Other Object in PowerPoint

You can now lock an image, shape or other object in PowerPoint. Objects can be locked in Normal View or Slide Master View. Only PowerPoint 365 users can lock objects to prevent moving and resizing. This is helpful if you want to select and move other objects on the slide or prevent others from moving or resizing an object. You can lock items using the context menu or the Selection Pane.

How To Get Free Access To Microsoft PowerPoint

E very time you need to present an overview of a plan or a report to a whole room of people, chances are you turn to Microsoft PowerPoint. And who doesn't? It's popular for its wide array of features that make creating effective presentations a walk in the park. PowerPoint comes with a host of keyboard shortcuts for easy navigation, subtitles and video recordings for your audience's benefit, and a variety of transitions, animations, and designs for better engagement.

But with these nifty features comes a hefty price tag. At the moment, the personal plan — which includes other Office apps — is at $69.99 a year. This might be the most budget-friendly option, especially if you plan to use the other Microsoft Office apps, too. Unfortunately, you can't buy PowerPoint alone, but there are a few workarounds you can use to get access to PowerPoint at no cost to you at all.

Method #1: Sign Up For A Free Microsoft Account On The Office Website

Microsoft offers a web-based version of PowerPoint completely free of charge to all users. Here's how you can access it:

• Visit the Microsoft 365 page .
• If you already have a free account with Microsoft, click Sign in. Otherwise, press "Sign up for the free version of Microsoft 365" to create a new account at no cost.
• On the Office home page, select PowerPoint from the side panel on the left.
• Click on "Blank presentation" to create your presentation from scratch, or pick your preferred free PowerPoint template from the options at the top (there's also a host of editable templates you can find on the Microsoft 365 Create site ).
• Create your presentation as normal. Your edits will be saved automatically to your Microsoft OneDrive as long as you're connected to the internet.

It's important to keep in mind, though, that while you're free to use this web version of PowerPoint to create your slides and edit templates, there are certain features it doesn't have that you can find on the paid version. For instance, you can access only a handful of font styles and stock elements like images, videos, icons, and stickers. Designer is also available for use on up to three presentations per month only (it's unlimited for premium subscribers). When presenting, you won't find the Present Live and Always Use Subtitles options present in the paid plans. The biggest caveat of the free version is that it won't get any newly released features, unlike its premium counterparts.

Method #2: Install Microsoft 365 (Office) To Your Windows

Don't fancy working on your presentation in a browser? If you have a Windows computer with the Office 365 apps pre-installed or downloaded from a previous Office 365 trial, you can use the Microsoft 365 (Office) app instead. Unlike the individual Microsoft apps that you need to buy from the Microsoft Store, this one is free to download and use. Here's how to get free PowerPoint on the Microsoft 365 (Office) app:

• Search for Microsoft 365 (Office) on the Microsoft Store app.
• Install and open it.
• Sign in with your Microsoft account. Alternatively, press "Create free account" if you don't have one yet.
• Click on Create on the left side panel.
• Select Presentation.
• In the PowerPoint window that opens, log in using your account.
• Press Accept on the "Free 5-day pass" section. This lets you use PowerPoint (and Word and Excel) for five days — free of charge and without having to input any payment information.
• Create your presentation as usual. As you're using the desktop version, you can access the full features of PowerPoint, including the ability to present in Teams, export the presentation as a video file, translate the slides' content to a different language, and even work offline.

The only downside of this method is the time limit. Once the five days are up, you can no longer open the PowerPoint desktop app. However, all your files will still be accessible to you. If you saved them to OneDrive, you can continue editing them on the web app. If you saved them to your computer, you can upload them to OneDrive and edit them from there.

Method #3: Download The Microsoft PowerPoint App On Your Android Or iOS Device

If you're always on the move and need the flexibility of creating and editing presentations on your Android or iOS device, you'll be glad to know that PowerPoint is free and available for offline use on your mobile phones. But — of course, there's a but — you can only access the free version if your device is under 10.1 inches. Anything bigger than that requires a premium subscription. If your phone fits the bill, then follow these steps to get free PowerPoint on your device:

• Install Microsoft PowerPoint from the App Store or Google Play Store .
• Log in using your existing Microsoft email or enter a new email address to create one if you don't already have an account.
• On the "Get Microsoft 365 Personal Plan" screen, press Skip For Now.
• If you're offered a free trial, select Try later (or enjoy the free 30-day trial if you're interested).
• To make a new presentation, tap the plus sign in the upper right corner.
• Change the "Create in" option from OneDrive - Personal to a folder on your device. This allows you to save the presentation to your local storage and make offline edits.
• Press "Set as default" to set your local folder as the default file storage location.
• Choose your template from the selection or use a blank presentation.
• Edit your presentation as needed.

Do note that PowerPoint mobile comes with some restrictions. There's no option to insert stock elements, change the slide size to a custom size, use the Designer feature, or display the presentation in Immersive Reader mode. However, you can use font styles considered premium on the web app.

Method #4: Use Your School Email Address

Office 365 Education is free for students and teachers, provided they have an email address from an eligible school. To check for your eligibility, here's what you need to do:

• Go to the Office 365 Education page .
• Type in your school email address in the empty text field.
• Press "Get Started."
• On the next screen, verify your eligibility. If you're eligible, you'll be asked to select whether you're a student or a teacher. If your school isn't recognized, however, you'll get a message telling you so.
• For those who are eligible, proceed with creating your Office 365 Education account. Make sure your school email can receive external mail, as Microsoft will send you a verification code for your account.
• Once you're done filling out the form, press "Start." This will open your Office 365 account page.

You can then start making your PowerPoint presentation using the web app. If your school's plan supports it, you can also install the Office 365 apps to your computer by clicking the "Install Office" button on your Office 365 account page and running the downloaded installation file. What sets the Office 365 Education account apart from the regular free account is that you have unlimited personal cloud storage and access to other Office apps like Word, Excel, and Outlook.
