Accessibility expectations are rising across Europe. PDF Accessibility Checker helps you find obvious accessibility risks before they become a bigger problem.
How it works
This free checker is designed as a quick first pass. It highlights likely issues, surfaces machine-detectable signals, and points to areas that may need manual review.
Add a PDF or URL
Start with a file upload or paste a direct PDF URL. No account is required for the basic check.
Run automated diagnostics
Machine-detectable checks look for missing structure, metadata gaps, screen-reader risks, and other likely issues.
Review the risk signals
See a plain-English summary of likely issues and a clearer picture of what may need fixing first.
What this free checker looks for
- Missing or weak PDF structure
- Missing title or language metadata
- Screen-reader risk signals
- Reading-order risk signals
- Image and alt text risk signals
Includes a 10-point PDF accessibility risk checklist covering tags, structure, language, title, image-only pages, bookmarks, and heading signals.
What automated checks cannot fully judge
- Reading order may still need human review
- Alternative text quality may need human review
- Legal compliance cannot be confirmed by this free tool
- WCAG, PDF/UA, ADA, and EAA compliance may require expert review
About this tool
PDF Accessibility Checker is designed to be a useful public starting point for reviewing machine-detectable PDF accessibility risks. It is intended to surface likely issues clearly, not to replace manual accessibility review.
Manual review still matters
Automated accessibility diagnostics are helpful for triage, but they cannot fully judge document meaning, reading order quality, or whether accessibility expectations have been fully met.
