PDFUA.io Validator
What PDFUA.io Validator is
PDFUA.io Validator checks PDF files against WCAG 2.1 AA and strict PDF/UA-1 (ISO 14289-1), while preserving evidence suitable for audits. You can upload files, validate batches up to 200 MB, or submit a public URL for fetching. Findings show severity, occurrence counts, structure path, page, PDF object and text snippets; a privacy setting can omit snippets. Reports contain verdicts, errors, warnings, engine version and a SHA-256 fingerprint, and stored validations can be rendered again. Monitoring discovers PDFs across domains, runs daily, weekly or monthly checks, and alerts about regressions, fetch failures and exhausted credits. Its HTTP API returns JSON or HTML for CI pipelines, document-management systems and other applications. Reports support English and French. Agency workspaces isolate clients, while enterprise deployment offers a stateless API container or self-hosted monitoring appliance. A free cloud plan includes 20 credits monthly; paid plans start at $19/mo.
