PowerPoint to PDF
Turn a .pptx deck into a PDF in your browser. The presentation is never uploaded.
- Runs on your device — the file is never sent anywhere
- No sign-up, no watermarks, no daily quotas
- Free, with no limit on how often you use it
How it works
A deck is usually shared long before it is finished, and sending it as a PDF is the easiest way to stop people editing it, reflowing it or opening it in a version of PowerPoint that moves everything. Every free converter that does this wants the file uploaded first. This one reads the .pptx in the page: a .pptx is a ZIP of XML, and everything needed to place the text and pictures is inside it.
How it works
A .pptx file is a ZIP archive. Inside it, every slide is an XML document that lists each shape along with its exact position and size, measured in English Metric Units. The tool unzips the file in memory, reads the slide size from the presentation itself, and rebuilds each slide as a PDF page at the same proportions — 16:9 or 4:3, whichever the deck uses. Text is drawn where the shape says it sits, and pictures are embedded at their own coordinates.
The text stays real text
Nothing is rasterised. Every word in the resulting PDF can be selected, copied, searched and read aloud by a screen reader. Bold and italic are kept, bullet levels are indented, and the font size recorded in the slide is honoured where the deck specifies one.
What is not reproduced — plainly
Theme backgrounds and colour schemes, fonts (everything becomes Helvetica, because a PDF must embed its fonts and yours may not be redistributable), charts, SmartArt, tables, WordArt, animations and slide transitions. Pictures in formats PDF cannot embed — EMF and WMF vector art pasted from Office, chiefly — are skipped, and the summary tells you how many. If the deck must look exactly as it does on screen, use PowerPoint's own File → Export → Create PDF, which has access to the fonts and the rendering engine that this page does not.
Speaker notes
Turn on the notes option and each slide's notes are added on their own page after it. That is the usual format for a handout, and it keeps the slide itself uncluttered.
Why it is private
The file is read with the browser's own ZIP and XML machinery. It is never sent anywhere, there is no server involved, and closing the tab discards everything. That matters more for decks than for most files — pitch decks, board packs and internal strategy slides are exactly the sort of thing that should not sit in a stranger's upload queue.
PowerPoint to PDF — questions
Does it work with .ppt files?
No. The old .ppt format is a completely different binary format, not a ZIP of XML, and it cannot be read here. Open it in PowerPoint, Keynote or LibreOffice and save it as .pptx first.
Will my slides look identical?
No, and the page says so rather than pretending otherwise. Text and picture positions are kept, but theme backgrounds, fonts and charts are not. Think of it as a readable, searchable record of the deck's content rather than a photograph of it.
Are my speaker notes included?
Only if you ask for them. By default the PDF contains the slides alone.
Is there a size limit?
Only your device's memory. A deck of a few hundred slides with large photographs will use a lot of it, because the whole file is decompressed in the page.
Does anything get uploaded?
No. There is no server to upload to. You can confirm it by opening your browser's network tools, or by turning off your internet connection once the page has loaded — the conversion still works.
