Why Use This PPTX to PDF Converter?
Built for accuracy, not just speed.
True-to-Size Pages
We read your presentation's actual slide dimensions and build PDF pages that exactly match — no stretched or distorted widescreen slides forced onto a mismatched paper size.
Complete Page Count
Every slide gets a corresponding PDF page, even if a slide has no extractable image — so your page count always matches the original deck.
Compression Control
Choose how aggressively images are compressed, so you can balance file size against visual quality.
100% Local Processing
Your presentation is never uploaded anywhere — conversion happens entirely on your own device.

Frequently Asked Questions
Why is one of my slides blank in the PDF?
This tool builds each PDF page from the rendered image embedded in your slide. Slides made up of live text boxes, shapes, or charts without an embedded full-slide image won't have that image to extract, so they appear as a blank page in the PDF — but the page itself is still included, so your page count always matches the original presentation.
Will my slide's aspect ratio be preserved?
Yes, by default. We read the actual slide width and height from your presentation file and size each PDF page to match exactly, avoiding the stretching that happens when a widescreen 16:9 deck is forced onto a fixed A4 page.
Is there a file size limit?
There's no fixed limit, since everything runs locally in your browser rather than being uploaded — though very large presentations will take longer to process and use more of your device's memory.
Is my presentation uploaded anywhere?
No. The file is read and converted entirely inside your browser using JavaScript libraries loaded on the page. It is never sent to any server.
