How the Conversion Works
A .pptx file is a ZIP archive of XML parts. This tool opens that archive in your browser, reads the slide XML directly, and rebuilds each slide as a page in a new PDF — at the presentation’s own page size, using the shape positions recorded in the file.
Nothing is uploaded. The archive is unpacked, read and re-rendered on your own machine, which matters because presentations routinely contain unreleased figures, client names and internal strategy.
What Carries Across — and What Does Not
Being specific about this saves you a wasted download. A faithful PowerPoint renderer has to interpret theme inheritance, layout placeholders and drawing transforms; that is a rendering engine, not a web page. This tool reproduces the substance of a deck rather than a pixel-match of it.
| Reproduced | Not reproduced |
| Slide order and slide count | Theme colours, gradients and backgrounds |
| Page size, including 16:9 widescreen | Exact typefaces (text is set in a standard PDF font) |
| All slide text, as selectable text | Charts, SmartArt and WordArt effects |
| Relative font sizes and bold | Tables (text is kept, grid lines are not) |
| Embedded PNG and JPEG images | Animations, transitions and speaker notes |
| Approximate shape positioning | Vector shapes drawn inside PowerPoint |
If you need an exact visual match, PowerPoint’s own File → Export → Create PDF is the right tool — it has the full rendering engine. Use this converter when you want the deck’s content as a shareable, searchable PDF without installing anything or handing the file to a server.
If You Have an Older .ppt File
The legacy .ppt format is a binary format that predates the ZIP-based standard, and it cannot be read this way. Open it in PowerPoint or LibreOffice and save it as .pptx first.
After Converting
Once you have the PDF you can merge it with other documents, compress it before emailing, add page numbers for a printed handout, or password-protect it before sending it outside your organisation. To brand every page with a template, see adding a letterhead or stamp to a PDF.
Frequently Asked Questions
Is my presentation uploaded anywhere?
No. The file is unpacked and converted entirely in your browser. Nothing is transmitted to a server, and nothing is stored.
Will the PDF look exactly like my slides?
No, and the table above sets out exactly where it differs. Text, images, slide order and page size carry across; themes, exact fonts, charts and vector shapes do not. For a pixel-perfect export use PowerPoint’s own Export to PDF.
Can I convert a .ppt file?
Not directly. Save it as .pptx in PowerPoint or LibreOffice first, then convert.
Is the text in the PDF selectable?
Yes. Slide text is written as real text, not as a picture of text, so it can be selected, copied and searched.
Is there a file size limit?
There is no imposed limit, but conversion runs on your own device, so very large decks depend on your machine’s memory.
