How to check a PowerPoint for accessibility

  1. Choose the presentation.
  2. Read the errors, warnings and tips, slide by slide.
  3. Fix them in PowerPoint and check again; download the results if you need a record.

What is checked

  • Every slide has a title, and titles are not empty or repeated.
  • Pictures, charts, SmartArt, embedded objects and videos have alternative text, unless they are marked as decorative.
  • Tables have a header row.
  • Text set smaller than 18 pt (only sizes set on the text itself, not sizes that come from the layout).
  • Slides with no text or pictures, link text that doesn't describe its destination, and a missing document title.

What isn't checked

  • Colour contrast, because it needs the slides drawn exactly as PowerPoint draws them.
  • Reading order: PowerPoint's own checker (Review › Check Accessibility) and the Selection Pane help with that.
  • Text inside pictures and captions in videos.
  • Whether alternative text is actually good: it should say what the picture shows or means.

Questions fréquentes

Does passing this check make my presentation accessible?

No automatic check can promise that. It finds common, clear-cut problems; a person still needs to check contrast, reading order and whether the alt text is helpful.

Can I use an old .ppt file?

No. The old PowerPoint 97–2003 format (.ppt) is a different kind of file. Open it in PowerPoint, Keynote, Google Slides or LibreOffice Impress, save it as .pptx, then use that file. To just look at a .ppt, use the PowerPoint Viewer.

Is my presentation uploaded?

No. Everything happens in your browser, on your device.
