Check and improve PDF accessibility

Many PDFs are hard or impossible to use with a screen reader. This tool checks yours against the basics, fixes what software can fix correctly — the document title, its language and a text layer on scanned pages — and lists plainly what still needs a person, such as tags and image descriptions.

  • Your files stay on your device

    Make PDF accessible runs in your browser, so nothing is uploaded — not the file, not even its name.

  • Free, with no sign-up

    No account, no watermark on your files and no daily limit for normal use.

  • Files up to 100 MB

    Large or scanned files are fine — they simply take a little longer.

  • Works on every device

    Windows, Mac, Linux, iPhone, iPad and Android, in any modern browser. Nothing to install.

Each file can be up to 100 MB. Large or scanned files simply take a little longer.
