Best Free PowerPoint to PDF

How it works

1. Upload. Choose a PowerPoint file — PPT, PPTX or ODP (up to 100 MB).
2. Convert. Press Convert to PDF — each slide becomes a page via LibreOffice.
3. Download. The PDF downloads automatically; the presentation is never stored.

About this tool

PowerPoint to PDF turns a PPT or PPTX presentation into a PDF, with each slide becoming a page. It uses LibreOffice on the server to render the deck, so the slide layout, fonts and graphics carry over faithfully. A PDF is the safe way to share a presentation when you want it to look identical for everyone and can't rely on the recipient having PowerPoint. Each conversion runs under a size cap and a hard time limit. No watermark, no signup, and the file is deleted right after.

What people use it for

• Share a deck as a PDF that looks the same for everyone
• Send slides to someone without PowerPoint
• Lock a presentation so it can’t be easily edited
• Produce a printable handout from a deck
