How to convert PPTX to PDF
- Add your files. Drop PPTX files anywhere on the page, or use Choose files. Folders and ZIP archives work too; every PPTX inside is picked up.
- Check that PDF is selected. PDF is already chosen on this page. Other formats in the same row are one tap away if you change your mind.
- Adjust options if you need to. There is nothing to set; the defaults are chosen for the best result.
- Convert and download. Press Convert. Each file shows its progress, then a Download button. With several files, “Download all” gives you a single ZIP.
What happens to your PPTX
Each slide is drawn in your browser by an open-source PowerPoint renderer and captured as an image, giving a PDF with one page per slide. Slide size and proportions are kept.
The renderer handles text, shapes, pictures, tables and backgrounds well; animations, transitions, embedded video and some charts or SmartArt are not reproduced, and fonts that are not installed on your device are replaced with similar ones. Because pages are images, the text in the PDF cannot be selected.
About PPTX and PDF
PPTX: PPTX is the Microsoft PowerPoint format, also used by Google Slides, Keynote and LibreOffice Impress.
PDF: PDF keeps a document’s layout fixed on every device, which is why it is used for forms, invoices and anything printed or signed.
Questions
Is my PPTX file uploaded anywhere?
No. The conversion runs inside this browser tab using code served by this site, and the PDF is created on your device. You can even disconnect from the internet once the page and its converter have loaded.
Why does a slide look slightly different?
Slides are drawn by an open-source renderer in your browser. Uncommon fonts are swapped for similar ones, and some charts, SmartArt and effects are simplified. For a pixel-perfect copy, export from PowerPoint itself.
Can I convert several PPTX files at once?
Yes. Drop as many PPTX files as you like, a whole folder or a ZIP. They convert one after another, and “Download all” saves every PDF in one ZIP that keeps your folder structure.
Is there a file size limit?
There is no fixed limit, because nothing is uploaded. The practical limit is your device’s memory: a phone may struggle with very large files that a laptop converts easily.
