Compress a PowerPoint file in your browser
Timamu Web makes a smaller copy of a .pptx or .ppsx presentation so it is easier to email or upload. It runs in your browser, and your presentation stays on your device.
How to compress a PowerPoint
- Open the PowerPoint compressor on Timamu Web.
- Choose a .pptx, .ppsx or .potx file from your device.
- Pick a compression level: Safe, Balanced or Strong.
- Download the smaller copy. Your original file is not changed.
Real limits
Free works on files up to 100 MB. Premium goes up to 2 GB. Works with .pptx, .ppsx and .potx.
Older .ppt files, Google Slides links and password-protected files aren't supported. Save a .ppt as .pptx first, or download a Google Slides deck as Microsoft PowerPoint (.pptx). Embedded videos are kept as they are, so a video-heavy deck may stay large.
Questions
Does my presentation stay on my device?
Yes. Timamu prepares your presentation in your browser on your device.
Is it free?
Yes. Timamu Web is the free way to compress a PowerPoint file, with no sign-up, for presentations up to 100 MB. Premium raises the limit to 2 GB.
Can I compress an old .ppt file?
Not directly. Open the .ppt in PowerPoint or Keynote, save it as .pptx, and then compress the .pptx with Timamu Web.
Will my slides look different?
Text, styles and charts stay the same. Timamu recompresses images, so on the Strong level photos may look softer; Safe keeps more detail.
Why is my compressed deck still large?
Embedded videos are kept as they are, so they can make up most of the file size. Compressing the images in the deck cannot shrink those videos.
