Convert PPS to PDF.
A .pps or .ppsx file is a PowerPoint Show — it launches straight into a slideshow, and won't open at all without PowerPoint. Turn it into a PDF anyone can read, print or attach.
The slideshow that won't open
Someone emails you a .pps (or the newer .ppsx) and your computer just shrugs. It's a "PowerPoint Show" — the exact same deck as a .ppt/.pptx, but saved to launch straight into full-screen presentation mode. Without PowerPoint installed, there's nothing to launch it with. Converting to PDF sidesteps all of that: you get a normal document, one page per slide, that opens on anything.
Read now, edit later
PDF is the right call when you just need to see the deck — review it, print a handout, or forward it. If you actually need to change the slides, convert to PPTX instead and open it in any modern slides app.

Common questions
What's the difference between PPS and PPTX?+
They hold the same slides — a .pps/.ppsx just opens directly in presentation mode instead of the editor. That's convenient if you have PowerPoint and confusing if you don't, which is why a PDF is often easier to share.
Is it free?+
Yes — convert PPS 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 get the editable slides back?+
If you need to edit rather than read, convert to PPTX instead — then open it in PowerPoint, Keynote or Google Slides.
