About Compress PPTX
Compress PPTX unpacks the presentation, saves the JPG, PNG and WebP images inside again at a lower quality when that makes them smaller, and packs the file back up at the highest ZIP compression. Slides, notes, fonts and videos stay as they were, and images keep their pixel size.
Frequently asked questions
Will speaker notes survive?
Yes. Only images are saved again, and notes, slides and layouts are left untouched.
Does it work on .ppt (legacy)?
No. The old .ppt format isn't a ZIP package, and the tool only accepts .pptx, so save the file as .pptx in PowerPoint first.
