Convert PowerPoint to PDF online, free
Turn a .pptx, .ppt, .pptm or .odp into a PDF where every slide is one page, at the size and shape you built it — 16:9 stays 16:9, 4:3 stays 4:3, and a custom slide size stays custom. Backgrounds, gradients, shapes, arrows, images, charts and tables all come through, and the text stays real text: selectable, searchable, and readable by a screen reader, rather than a flat picture of a slide.
Fonts matter more in a deck than anywhere else
A presentation is mostly large type on a coloured background — there is nowhere for a bad substitution to hide. A .pptx stores the names of its fonts and expects the machine opening it to have them, which on a conversion server it does not. This tool carries proper stand-ins for the fonts Microsoft ships — Calibri, Cambria, Aptos, Segoe UI — matched by the kind of typeface each one is, so your titles do not arrive in a serif you never chose.
The failure this prevents is not hypothetical
Aptos, the default font in current versions of Office, resolved to a serif face on a stock conversion setup until it was fixed here. That is the difference between a deck that looks like your deck and one that merely contains your words. If your presentation carries its own embedded fonts, they render exactly, with no substitute involved at all.
Arabic, Hebrew and Persian decks
Right-to-left text keeps its direction and its letter shaping, and the fonts resolve to real faces for those scripts rather than to one generic fallback — the failure that normally makes an Arabic deck arrive looking nothing like the original.
What you can do with the result
Send it to a client, attach it to an email, or hand it to a printer without anyone needing PowerPoint at the other end. Speaker notes are deliberately left out: the PDF contains the slides as your audience sees them, which also means you are not accidentally publishing notes you wrote for yourself.
Speed and batches
An eight-slide deck converts in about half a second. Convert up to 10 presentations in one request, 300 MB in total. One deck comes back as a PDF; several come back as a ZIP with one PDF per presentation, each named after the file it came from. Choose PDF/A if the deck is going into an archive, and everything is deleted from the server an hour later.
What you get
- One slide per page at your own aspect ratio — nothing cropped or letterboxed
- Fonts substituted by typeface kind, never a serif for a sans
- Embedded fonts rendered exactly
- Real right-to-left support for Arabic, Hebrew and Persian decks
- Selectable, searchable slide text — and speaker notes left out on purpose
- Up to 10 presentations and 300 MB per request, with PDF/A available
What's next?
Documents and spreadsheets need different handling and have their own pages: Word to PDF focuses on font fidelity, and Excel to PDF solves page layout for files nobody set up for printing. Archiving the deck? Convert to PDF/A. And if the PDF is heavier than you need, Compress PDF brings it down.
