What accessibility standards does this check?

The tool evaluates PDFs against WCAG 2.1 AA guidelines, Section 508 requirements (US federal accessibility law), and PDF/UA-1 (ISO 14289-1) standards. It checks for tagged structure, alt text, reading order, heading hierarchy, language settings, and more.

Who needs accessible PDFs?

Government agencies in the US (Section 508), EU public sector bodies (EN 301 549), educational institutions, publicly traded companies, and any organization serving people with disabilities. Accessible PDFs work with screen readers and assistive technologies used by people with visual, motor, and cognitive impairments.

Can this tool fix accessibility issues?

This tool identifies and reports issues with specific recommendations for fixing them. It does not automatically fix issues, as many accessibility fixes require human judgment (like writing appropriate alt text for images). Use the report as a checklist for remediation.

PDF/UA (Universal Accessibility) is an ISO standard (14289-1) defining requirements for accessible PDF documents. It specifies that PDFs must have proper tag structure, alternative text for images, defined reading order, and other features that enable assistive technologies to present the content to users with disabilities.
