PowerPoint to PDF
Convert PowerPoint presentations to PDF online for free. All slides preserved, no quality loss. No signup, no software download. Files stay private in your browser.
PPT to PDF converts PowerPoint .pptx and .ppt files into high-fidelity PDF documents, rendering each slide as a full-page PDF with text, shapes, images, gradients, and SmartArt faithfully reproduced. The conversion runs in your browser using a combination of PptxGenJS parsing and canvas-based rendering — no file upload required, and no loss of slide-level content. Multi-slide decks are handled automatically, with each slide becoming one PDF page at the selected output resolution (72, 150, or 300 DPI for print-quality output).
PowerPoint slide aspect ratios vary — 4:3 (standard), 16:9 (widescreen), 16:10 — and most online converters force everything to A4 or Letter, distorting the layout. This tool preserves the original slide dimensions: a 16:9 deck becomes a 16:9 PDF with no letterboxing or cropping. Speaker notes can optionally be included as text below each slide (like PowerPoint's own Notes view export), making the PDF useful as a handout without the presenter notes appearing during the presentation.
Features
- Aspect ratio preservation — 4:3, 16:9, and 16:10 slides render in their native proportions without letterboxing
- Speaker notes export — optionally include notes below each slide for handout-style PDFs
- High-resolution output — 72 DPI (screen), 150 DPI (screen-quality), or 300 DPI (print-quality)
- SmartArt and shape rendering — flowcharts, org charts, timelines, and callouts render as static shapes
- Image and gradient fidelity — background images, gradient fills, and photo placeholders render cleanly
- Multi-slide batch — entire decks converted in one pass, each slide = one PDF page
- Slide range selection — convert specific slides (e.g., 3-7) rather than the whole deck
- Runs in browser — presentation file never uploaded
How to use PowerPoint to PDF
- Drop your .pptx file into the upload zone. The tool parses the slide structure and shows a thumbnail grid.
- Choose output settings: resolution (72/150/300 DPI), whether to include speaker notes, and whether to convert all slides or a range.
- Click Convert to PDF. Rendering takes 1-3 seconds per slide at 150 DPI — a 40-slide deck typically converts in under 90 seconds.
- Review the thumbnail strip in the preview. Spot-check slides with complex layouts (SmartArt, charts) to verify fidelity.
- Download the PDF. For print use, verify resolution at 100% zoom before sending to a print shop.
Frequently asked questions
Why do some fonts look different in my PDF?
If the presentation uses fonts not installed on your device (or embedded in the PPTX), the browser substitutes the nearest available font. To prevent this, embed fonts in your PPTX before converting: in PowerPoint, go to File → Options → Save → check "Embed fonts in the file."
Do animations convert to PDF?
No — PDFs are static documents. Animations, transitions, and interactive elements are captured as their end-state appearance (how the slide looks when fully loaded). If you need motion, export the deck as an MP4 in PowerPoint instead.
Can I convert just a few slides instead of the whole deck?
Yes. Enter a slide range (e.g., "5-12" or "1, 3, 7-9") after opening the file to convert only those slides. Useful for extracting a specific section of a long deck.
What is the maximum file size supported?
Files up to 150MB are handled. Very large decks with many high-resolution images embedded may be slower to parse — allow up to 60 seconds for 100MB+ files. Decks with thousands of slides (unusual but possible) should be split into sections first.
Why does my background image look blurry?
The output DPI determines image sharpness in the PDF. At 72 DPI, background images may look soft on high-resolution screens. Switch to 150 or 300 DPI for crisper output — the tradeoff is a larger file size.
