Convert PPSX to PDF.
A .ppsx file is a modern PowerPoint Show — it opens straight into a slideshow and needs PowerPoint to run. Convert it to a PDF that opens, reads and prints anywhere.
A show that needs the right software
The "x" in .ppsx marks it as the modern XML-based PowerPoint Show, the slideshow sibling of .pptx. It's designed to launch a presentation the moment you open it — handy on a machine with PowerPoint, useless on one without. A PDF makes the deck universally readable, one page per slide.
Share without the friction
Whether you're emailing a deck for review or printing handouts, PDF removes the "do you have PowerPoint?" question entirely. To keep editing the slides instead, convert to PPTX.

Common questions
How is PPSX different from PPTX?+
Same slides, different behaviour: a .ppsx opens directly in full-screen presentation mode, while a .pptx opens in the editor. Both need PowerPoint-compatible software — which is why a PDF is the easiest thing to pass around.
Is it free?+
Yes — convert PPSX to PDF free, with no signup. Paid plans add larger files and batch.
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.
Can I edit the slides instead?+
Convert to PPTX if you need to edit them in PowerPoint, Keynote or Google Slides.
