PDF/A & PDF/UA validator online

Drop in a PDF and run it through veraPDF, the ISO reference validator for PDF/A and PDF/UA. We host veraPDF so you don't have to install Java to spot-check one document. Same engine, same rule set, no install.

We don't keep your uploads. The PDF is held in memory for the length of one request, validated, and discarded as soon as the report renders. Nothing lands in cloud storage.

Profiles:PDF/A-2APDF/UA-1

Privacy: processed in-memory, discarded after the report renders. No R2 capture, no DB rows, no logging of file content. The /validate page surfaces the same promise that /enhance honours; only the upload path differs.

Powered by veraPDF 1.28.2. The validation rules and result text come from the veraPDF Consortium. This page is a hosted wrapper; the engine is theirs.

Programmatic access: POST /api/v1/pdf/validate · base64 JSON body · IP rate-limited (30 / hour). Validation is the only unauthed endpoint under /api/v1/* — see API docs.
