PDF Accessibility Checker

Check a PDF for accessibility signals.

Select a PDF to review its tags, language, title, bookmarks, forms, images, and text signals. The file stays on your device.

Private by design: analysis runs in your browser and the PDF is not sent to AuditYourWeb. This preflight cannot certify PDF/UA or WCAG conformance; manual reading-order and screen-reader testing is still required.

Choose a PDF up to 25 MB. Nothing is uploaded.

What to fix

Turn the scan into practical accessibility work.

Automated testing is a starting point. AuditYourWeb keeps the guidance direct so owners, agencies, and developers can decide what to fix next without pretending automation is legal certification.

Run the free checker

Add and validate a logical tag tree with correctly nested headings, lists, tables, and paragraphs.

Set the document title, primary language, and initial view to display the document title.

Add meaningful alternative text to informative figures and mark decorative content as artifacts.

Check reading order, keyboard navigation, form labels, color contrast, and reflow in a full PDF accessibility tool.

Where it fits

From one free scan to a repeatable accessibility workflow.

Use this private browser-based preflight before completing manual checks with a screen reader and a full PDF/UA validation workflow.

The public checker is free to use. Saved websites, widget setup, deep scans, and code issue tracking live in the dashboard when your team needs a longer workflow.

FAQ

Common questions about free PDF accessibility checker.

Is this PDF accessibility checker really free?

Yes. The preflight runs in your browser without uploading the document. It checks common structural signals and does not require an account.

Does a passing result prove that my PDF is accessible?

No. Automated checks cannot confirm reading order, accurate alternative text, table headers, color contrast, keyboard behavior, or screen reader usability. Manual testing is still required.

What does the online PDF accessibility checker inspect?

It looks for PDF tags, a structure tree, document language and title metadata, title display preferences, bookmarks, forms, images, text signals, and encryption indicators.
