Questions people ask
Are my files uploaded?
No. Everything happens inside your browser on this device. Nothing is sent anywhere, and nothing is kept after you close the page.
What gets smaller?
Only the pictures: they are resized to a sensible size for screens and resaved. Photos saved as PNG become JPEG. Parts nothing uses any more are removed.
Why did my file barely shrink?
Videos and sound are not changed. If a deck is big because of a video, shrink the video with the Video converter and insert it again.
Does it work with old .ppt files?
This tool works with .pptx, the format PowerPoint has used since 2007. Turn an old .ppt into .pptx first with the Presentation converter.
