Optimize and compress multimedia in PowerPoint

When a PowerPoint presentation starts to get too big, sharing it via email or moving it between computers becomes a bit of a headache; The good news is that there are several reliable ways to compress videos, audio and images without destroying the design.

In this guide, we've compiled and rewritten the most useful elements of the best textbooks on the subject so you have everything at your fingertips: native PowerPoint compression on Windows, image size reduction, tweaks that shave megabytes, and online and desktop alternatives when you need more control. The goal is to make playback smooth and the file as light as possible..

What does it mean to compress multimedia in PowerPoint and when to use it?

PowerPoint incorporates a system to reduce the size of embedded elements (video and audio), which improves playback performance and saves disk space; This media compression feature exists in PowerPoint for Windows, but is not available in Mac not even in the web version.

It is convenient to apply it when you have inserted clips with a higher resolution than you really need or when the presentation starts to go jerkily on less powerful teams; Compression adjusts the quality and resolution of the video and audio to make the whole thing more bearable..

One important detail to keep in mind: when compressing certain embedded videos, PowerPoint may remove attached tracks such as embedded subtitles or alternative audios; If your clip includes them and they are essential, consider keeping a copy of the original or using an external alternative that preserves those tracks..

  3. Choose the profile you prefer: Full HD quality (1080p), HD (720p) o Standard (480p)The lower the resolution, the greater the space savings.
  4. A window will open with the progress bar and when finished you will be able to close it to apply the changes throughout the presentation.

Global settings that cut megabytes without affecting the design

Beyond compressing image by image, PowerPoint has preferences that affect the entire document and help you keep file size down; These changes are especially useful if you edit many photos within the presentation.:

  • Active Discard edit data (You will no longer be able to restore the photo to its initial state in that file, but the savings are noticeable.)
  • Make sure that Do not compress images in the file is unchecked, otherwise no optimization will be applied.
  • En Default resolution, choose 150 dpi or less if the presentation will be viewed on screen or emailed.

Reduce the size of embedded fonts

To make your PPT look the same on computers that don't have your fonts, you can embed the fonts, but that makes the file bigger; minimize the impact by inserting only the characters used:

  1. Sign in File> Options> Save.
  2. En Maintain fidelity when sharing this presentation, Mark Embed fonts in file tab and activate Insert only the characters used.
