Make your PDF accessible to everyone, including people who use screen readers.

Upload a PDF. PDF Accessibility recognises the text on scanned pages, tags the document's structure, fixes headings, title and language, and drafts a description for every image. Check the descriptions yourself before it builds the accessible file, or accept them as drafted.

Upload. Scanned pages get text recognition (OCR). The PDF is tagged so headings, paragraphs, lists, tables and figures can be told apart.
Review. Check the drafted description for each image. Edit it, regenerate it, or mark the image decorative. Or skip this step and accept the AI descriptions.
Download. Get the accessible PDF, with its title, language and bookmarks set, and a report of what was checked.

Only the cropped figures and the text around them are sent to the AI service, never the whole PDF. Files are deleted after 24 hours, or as soon as you choose.

You're using guest mode: everything works, but files are deleted after 24 hours. Sign in or create an account to keep a history of your documents.

What do you want to do? Make accessible from scratch Text recognition for scans, tagging, title and language, and a description for every image. Review alt text in a tagged PDF Keeps the PDF's existing tags. For each image, keep its alternative text, edit it or regenerate it with AI. Images with none get an AI draft.

Drop PDFs here Up to 5 files. Choose files. Each up to 100 MB and 1000 pages.

Options

Document title

Leave empty to use the title already in the PDF, or its file name.

Language code

For example en-US, fr or de-AT. Leave empty to keep the PDF's own language.

Draft new descriptions for figures that already have alternative text

Skip image review and accept the AI descriptions

The accessible PDF is built as soon as the descriptions are drafted. Images the AI could not describe still come to you for review.
