PPTX to PDF Converter — Free, No Watermark

A free PPTX to PDF converter: each PowerPoint slide becomes one PDF page, the same size as the slide, with its text, bullets, pictures, shapes and tables where you put them. Converted in your browser, so the deck is never uploaded.

Settings appear once you add a presentation.

Include hidden slides Slides hidden in PowerPoint are left out unless you turn this on.

Done on your device No upload, no queue, no sign-up.

How to convert PPTX to PDF free, slide for slide

Your presentation goes into this browser tab, is drawn slide by slide on your device, and comes back as a PDF. 0 bytes uploaded
  1. Add your presentations

    Drop a .pptx file, or several decks at once.

  2. Check the settings

    Hidden slides are left out, as in a slideshow; switch Include hidden slides on to keep them.

  3. Save the result

    Press Make PDF. Every slide is one page at the slide’s own size and shape, 16:9 or 4:3, with its text still selectable.

Why it doesn’t upload

Decks carry what isn’t public yet: pitch numbers, product plans, pricing, reorganizations. Converting one in your browser keeps the slides on your device instead of a conversion server’s.

Worth knowing

  • Charts, SmartArt, video and 3D models aren’t drawn yet. Text, pictures, filled shapes, lines and tables are.
  • Text is set in Noto Sans or Noto Serif, matched to the theme’s font. A line can break a word earlier or later than PowerPoint’s.
  • Rotated text boxes are drawn upright, and gradient fills use their first color.
  • Speaker notes aren’t included; the PDF is the slides as the audience sees them.
  • Old .ppt files (PowerPoint 97–2003) need saving as .pptx first.

Under the hood

What happens to your file

The PPTX is read part by part — each slide, its layout and master, and the theme’s colors and fonts — and drawn with its backgrounds, text boxes, bullets, pictures, shapes and tables. One slide becomes one PDF page with real text. Charts, SmartArt and video are left out, and the tool page says so.

Questions

How do I convert PowerPoint to PDF for free?

Drop the .pptx here and press Make PDF. Each slide becomes a page. No watermark, no sign-up, no slide limit.

Will my fonts and layout be kept?

The layout is: every text box, picture and shape sits where it is on the slide. Fonts are swapped for the closest Noto font, sans or serif, at the same size.

Does it keep hyperlinks?

Yes. Links on slide text stay clickable in the PDF.

Can I convert several presentations at once?

Add them all; each becomes its own PDF, and Save all as ZIP downloads them together.

How do I turn a PDF into PowerPoint slides?

That’s PDF to PowerPoint: every PDF page becomes a slide.
