PDF Accessibility Checker
Inspect a PDF locally for a few machine-detectable accessibility signals, including document tags, metadata, selectable text, figures without alternate text, and heading-level jumps. This is only a first-pass checker, not a PDF/UA validator or a substitute for assistive-technology testing.
What can this PDF accessibility checker detect?
It reports whether the PDF exposes structure tags, a document title and language, selectable text on each page, figures with alternative text, and possible jumps in heading levels. It cannot decide if reading order or alternative text is meaningful.
Frequently asked questions
What can this PDF accessibility checker detect?
It reports whether the PDF exposes structure tags, a document title and language, selectable text on each page, figures with alternative text, and possible jumps in heading levels. It cannot decide if reading order or alternative text is meaningful.
Is my PDF uploaded for checking?
No. The selected PDF is inspected in this browser tab. The file and its text are not uploaded, saved automatically, or sent to a server.
Does a positive result mean the PDF is accessible?
No. These are limited automated signals only. A tagged PDF can still have incorrect reading order, poor descriptions, inaccessible forms, low contrast, or other barriers. Manual and assistive-technology testing is still needed.
Can it confirm PDF/UA or WCAG compliance?
No. This first-pass checker does not test every requirement and cannot certify PDF/UA, WCAG, Section 508, or legal compliance.
