Compress media to decrease file size
Trimming an audio or video clip affects only the playback of the media on the slide, not the original media clip. The original media clip is stored in its entirety as part of the presentation, and you can re-trim or restore the media clip at any time.
You can decrease the size of a PowerPoint file that contains trimmed media clips by discarding the unused portions of the clips. PowerPoint 2016 offers three compression configurations designed to balance size and quality.
Choose the size and quality that best fits your needs
When you save and close the file after compressing the media, the trimmed portions of the videos are discarded and no longer available. You can reverse the compression operation until you save and close the file.
Hyperlink to additional resources
Presentations often include URLs of websites that provide additional information related to the presentation topic. When a presentation will be viewed electronically, the URLs can be formatted as hyperlinks so that the websites can be accessed directly from the presentation. Hyperlinks can also provide access to information that might be on a hidden slide in the presentation, or in a separate file.
TIP If you use Microsoft Outlook, you can also use a hyperlink to open an email message window so that people viewing the presentation can easily contact you.
Hyperlinks are most frequently in text format, but you can attach a hyperlink to any object—for example, an image such as a shape, logo, or picture. Clicking the hyperlinked object then takes you directly to the linked location. Editing the object does not disrupt the hyperlink; however, deleting the object also deletes the hyperlink.
The simplest method of creating a hyperlink is to enter a URL in a text box and then press the Enter key. PowerPoint automatically inserts the hyperlink and formats the URL so that people recognize it as a hyperlink.
If you want the same hyperlink to appear on every slide in a presentation, attach the hyperlink to text or an object on the presentation’s master layout. For information about slide masters, see “Customize slide masters and layouts” in Chapter 12, “Create custom presentation elements.”
To attach a hyperlink to an object, follow these steps:
- Select the object that you want to hyperlink from.
Open the Insert Hyperlink box by doing either of the following:
- On the Insert tab, in the Links group, click Hyperlink.
- Press Ctrl+K.
In the Link to list, click the type of target you’re linking to. Often this is a webpage or another place in the file.
- If you’re linking to a webpage, enter the URL in the Address box. If you’re linking to a slide or heading in the current file, click it in the Select a place in this document pane. Then click OK.

To compress media files
Save the PowerPoint presentation, and then display the Info page of the Backstage view.
- Note the total size of the presentation, the size of the media files in the presentation, and the number of files that have been trimmed.
On the Info page, click the Compress Media button, and then click the level of compression you want. In the Compress Media window, PowerPoint itemizes the media elements and their compression levels, and reports the total space savings.
Compressing media files can make a big difference in file size
In the Compress Media window, click the Close button. In the Media Size And Performance area of the Info page, the Compress Media button is active to indicate that media has been compressed, and specifics about the compression are available.
You can undo the compression if you don’t like the results
- Play the presentation to assess the quality, and then save the file if the quality is acceptable.

To reverse the compression of media files
- On the Info page, click the Compress Media button, and then click Undo. PowerPoint immediately reverts to the uncompressed files.
