PowerPoint to PDF

Convert PPTX presentations entirely in the browser with one PDF page per slide. NGPDFs preserves source slide dimensions, order, backgrounds, positioned text, basic shapes, connectors, PNG/JPEG images, theme colors, and z-order while clearly reporting font, gradient, group-transform, animation, chart, and SmartArt limitations.

Compatibility report

NGPDFs reports what this browser-local renderer can reproduce; it does not claim pixel-perfect source pagination.

Preserved

  • slide dimensions
  • slide order
  • background colors
  • positioned text boxes
  • basic shapes
  • line styles
  • PNG/JPEG images
  • theme colors
  • z-order

Approximated

  • gradient fills
  • source fonts
  • mixed text-run styling
  • group transforms
  • text autofit

Omitted

  • master/layout-only objects
  • shape rotation and shadows
  • animations
  • transitions
  • speaker notes
  • charts
  • SmartArt
  • embedded objects
  • macros

Each PDF page keeps the source slide dimensions and orientation. No document theme, margins, or page numbers are imposed over the presentation.

How it works

  1. 1Choose a PPTX presentation; legacy PPT and macro-enabled files are intentionally not advertised.
  2. 2The worker reads slide order, dimensions, theme colors, drawing positions, text, shapes, connectors, and local media without running active content.
  3. 3Each source slide becomes one PDF page at the original slide size.
  4. 4Detected fidelity gaps are disclosed and the page count is validated before download.

Your privacy

This tool runs entirely inside your browser using JavaScript and Web Workers. Your document is never uploaded to any server — you can even disconnect from the internet and keep working once the page has loaded.

Frequently asked questions

▸Will animations and transitions appear?

No. PDF pages are static, so animations and transitions are intentionally omitted and disclosed.

▸Does it exactly match PowerPoint?

Not always. Proprietary fonts use deterministic fallbacks, gradients and grouped transforms are approximated, and charts, SmartArt, speaker notes, and embedded objects are not rendered in this first local adapter.

▸Can presentation code run?

No. Only PPTX Open XML content and supported local image media are read; scripts and macros are never executed.
