EqualWeb PDF Tools vs PAC (PDF Accessibility Checker)

EqualWeb PDF Tools combines PDF accessibility checking, automated remediation, expert manual remediation, and an accessible in-browser viewer. Its checker performs more than 80 automated checks across eight categories and returns a score from 0 to 100 with a detailed report. AI remediation can address document structure, reading order, alternative text, tables, forms, fonts, text encoding, contrast, language, and metadata. Scanned PDFs can receive OCR and remediation, up to 400 pages. Batch processing supports up to 1,000 PDFs; individual files can be as large as 400 pages and 100 MB, though larger files may be uploaded and flagged during an audit. Word, Excel, and PowerPoint files can be converted to accessible PDF or HTML, and PDFs to accessible HTML. The product says it remediates and validates against WCAG 2.2, PDF/UA-1 and PDF/UA-2, Section 508, and EN 301 549. A REST API handles uploads, audits, reports, remediation, downloads, and batches, with access requested from EqualWeb. Auto AI Tag is optimized for English and Latin-script documents.

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.
