Normfluss vs PAC (PDF Accessibility Checker)

Normfluss checks PDF documents for accessibility, applies structural fixes, and provides a signed record describing the checks and decisions made. It evaluates PDFs against PDF/UA-1 and the parts of WCAG 2.2 AA that apply to PDF files. The platform can automatically handle tags, reading order, and tables; people review judgment calls in a guided editor. A self-hosted model drafts image descriptions in English, French, German, or Dutch, but a person must accept each suggestion before it is applied.

Users can check up to 25 PDFs at once for free. Files may be up to 100 MB and 150 pages without an account, or 1,000 pages with a free account. A remediated file can be downloaded with a signed evidence record. Normfluss offers a REST API and HMAC-signed webhooks. Processing takes place in the EU; the maker says models are self-hosted, files are not used for training, and no third-party AI is used. Unauthenticated free-check files are deleted after 72 hours; account documents remain until deleted. Plans include a free check and one-time credit bundles from €50, paid once. The platform reports technical conformance, not legal certification or advice.

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.
