Why convert PPTX to PDF?
Sending slides as PDF means anyone can open them on any device without PowerPoint, the layout cannot shift, and the file is easy to print or upload. Teachers, universities and clients often ask for presentations as PDF.
When to keep the PPTX
Keep the PPTX for presenting and editing: PDF does not play animations, transitions or videos.
Tips for the best result
- Each slide becomes one page.
- Use common fonts in your slides so text keeps its exact size and line breaks.
- Embedded videos and sounds cannot play in a PDF.
Common problems and fixes
- Animated parts all appear at once.
- A PDF page shows the slide in its final state. Split builds into separate slides if the order matters.
- A font looks different.
- Fonts not installed on the server are replaced. Embed fonts when saving in PowerPoint, or use standard fonts.
PDF – Portable Document Format
PDF is the standard format for documents that must look the same on every device. It preserves layout, fonts and images, but is difficult to edit.

How do I convert PPTX to PDF?
Click Select File or drop your PPTX file onto the upload box. The converted PDF appears in the list below with a download button. You can add many files at once and download them together as a ZIP.
Is it really free?
Yes. There is no sign-up and no watermark. To keep the service available for everyone there is a 95MB limit per file and a cap on how many files one connection can process in a short period.
Are my files stored?
Your upload is used only to make the converted file. Images are processed in memory; other files are written to a private temporary folder that is deleted as soon as the conversion finishes. Nothing is kept after the result has been sent back.
Will quality drop?
For images, a little, by design: the image is re-encoded at the Quality you choose (default 75%). Audio and video are re-encoded with high-quality settings; documents keep their text and layout as far as the target format allows. Converting never restores detail that is already missing from the original.
How this works: your file is uploaded over HTTPS and converted on this server with open-source engines (libvips for images, FFmpeg for audio and video, LibreOffice and Pandoc for documents, Calibre for ebooks, Ghostscript and Inkscape for PDF and vector files). Images are processed in memory; other files use a private temporary folder that is deleted as soon as the conversion finishes.
