Convert PPS to PPTX.
A PowerPoint Show (.pps/.ppsx) opens straight into a slideshow and resists editing. Convert it to a standard PPTX you can actually open, edit and reuse in any slides app.

Get the edit button back
It's a familiar frustration: someone sends a deck as a .pps, you want to tweak a slide, and PowerPoint keeps launching it as a full-screen show instead. Nothing's actually locked. It's just saved in "show" mode. Converting to .pptx flips it back to a normal, editable presentation.
Reuse a template or a past deck
This is the conversion you want when you've been handed a show and need to update the figures, swap the branding, or lift a few slides into your own deck. If you only need to read it, convert to PDF instead.

Common questions
Why won't my PPS let me edit it?+
A .pps/.ppsx is saved as a 'show'. It's designed to launch into presentation mode rather than open in the editor. The slides themselves are the same as a normal deck; converting to .pptx just changes how it opens, giving you full editing back.
Is it free?+
Yes. Convert PPS to PPTX free. No signup and no watermark. Free covers 10 server conversions a day, up to 100 MB a file. Pro removes the daily limit and raises the file limit to 2 GB.
Is my file private?+
Uploads go to a private bucket, are converted, and auto-delete after 1 hour. Files never touch a third-party converter.
I just want to read it, not edit?+
Then convert to PDF instead. It's the simplest way to view, print or share the deck.
