PowerPoint to PDF

Convert .pptx slides to a PDF right in your browser — one page per slide at the real slide size, with text and images placed approximately. Best-effort, no uploads.

Loading tool…

A .pptx file is a zip containing one XML document per slide, and those documents describe shapes: a title box here, a bulleted body there, a picture at these coordinates. This tool reads them directly — no Office, no LibreOffice, no conversion service — and draws one PDF page per slide at the deck's real dimensions, so a 16:9 presentation produces 16:9 pages rather than slides letterboxed onto A4.

It is a best-effort renderer and says so. Text and pictures are placed approximately where the slide puts them; animations, slide transitions, SmartArt, charts and video are not drawn at all. For circulating a deck as a readable document — the usual reason anyone converts one — that is enough. For a printed proof of a designed presentation, open it in PowerPoint and export from there.

How it works

  1. Drop in a .pptx file.
  2. Page through the preview to see how the slides came out.
  3. Download the PDF — one page per slide, at the slide's own size.

What people use it for

  • Emailing a deck to someone who should read it but must not edit it.
  • Attaching slides to a report or a grant application that only accepts PDFs.
  • Archiving a presentation in a format that will still open in ten years.

Frequently asked questions

Is my file uploaded to a server?
No. The file is opened by JavaScript and WebAssembly running inside your own browser tab. It is never uploaded, there is no server-side processing and nothing is stored — closing the tab discards everything.
Will it look exactly like PowerPoint?
No, and the tool is explicit about that. Text and images are placed approximately; theme fonts are substituted; charts, SmartArt, animations and transitions are not rendered. Text-and-picture slides come out well, heavily designed slides come out simplified.
Are speaker notes included?
No. The PDF contains the slides themselves. Notes live in a separate part of the file and are left out, which is usually what you want when sending a deck to someone else.
Can I convert an old .ppt file?
No. The pre-2007 binary .ppt format is not the same container. Open it in PowerPoint or LibreOffice Impress and save as .pptx first.
Why is my page size not A4?
Because it is the slide's size. A widescreen deck is 33.87 × 19.05 cm, and forcing that onto A4 would either add wide margins or crop it. If you need A4, run the result through the Normalize page size tool.
