FAQ

What accessibility standards does it check?
The checker evaluates against WCAG 2.1 (Web Content Accessibility Guidelines) and PDF/UA (ISO 14289), which are the standards required by most government agencies and institutions.
What issues does it detect?
Common issues include missing document title, missing alt text on images, incorrect reading order, missing language declaration, poor heading structure, and insufficient color contrast.
Can it fix accessibility issues automatically?
The checker identifies and reports issues but does not modify your PDF. You will need to fix the issues in your PDF authoring tool (Word, InDesign, Acrobat) and re-check.
Is my PDF uploaded to a server?
No. The accessibility analysis runs entirely in your browser. Your document stays on your device.
Who needs accessible PDFs?
Government agencies, educational institutions, healthcare organizations, and any entity subject to ADA, Section 508, or EU accessibility directives must publish accessible documents. It is also good practice for any public-facing content.
