DocAccessible vs PAC (PDF Accessibility Checker)

DocAccessible helps teams check, rebuild, review, publish and exchange accessible documents through web and API. It can provide hosted accessible HTML and a rebuilt tagged PDF from remediated content. Automated checks map to WCAG 2.2 AA, while generated PDFs are PDF/UA-aligned rather than certified for conformance. The browser editor supports changes to headings, alt text, reading order, captions and table structure, then reruns checks when changes are saved. Exchange provides case-scoped vendor access, review and approval steps, version history and controlled delivery links; vendor remediation fees are separate. Website monitoring finds public PDF links and tracks source changes, but conversion and publication are separate actions. Security controls described include private production object storage, upload scanning with ClamAV, scoped permissions and versioned records. The Free plan accepts files up to 10 MB; Pro accepts files up to 50 MB. Plans range from free to $199 a month, with paid plans from $19 a month. There is no free trial.

PAC (PDF Accessibility Checker) is a free Windows desktop application for assessing PDF accessibility. Its Free plan costs nothing and includes PDF/UA and WCAG checks, quality checks, and AI-assisted checks. PAC covers WCAG 2.2 and combines automated scans with manual review tools. It also provides remediation guidance for addressing accessibility issues. The application is made by PAC (PDF Accessibility Checker), founded in 2010 and headquartered in Zurich, Switzerland. Windows is the listed platform. Mobile testing, a browser extension, and CI/CD integration are not included among its capabilities. The stated product scope is PDF accessibility checking, with checks aimed at PDF/UA and WCAG requirements rather than broad application testing. For Windows users reviewing PDF files, the free plan brings automated analysis, reviewer-led assessment, quality checks, AI-assisted checks, and guidance for remediation into one desktop application. Its feature set is focused on document accessibility rather than multi-platform testing.
