Questions

How do I convert PPSX to PPTX?

Drop your PPSX file on this page, or choose it. Anyfile converts it on your device in a moment and the PPTX downloads straight away. To change it first, open it in the presentation editor.

Is my PPSX file uploaded anywhere?

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.

Will the animation still play?

Yes. Every frame and its timing are kept in the PPTX.

Can I convert several PPSX files at once?

Yes. Drop them together and you get one ZIP with every PPTX inside.
