PDF/UA check with veraPDF — free, and an automatic fix for the metadata failures

Check your PDF against PDF/UA-1 — free

Runs veraPDF unmodified · result in about 20 seconds (the first check after a pause takes longer) · the file is not stored

Fixed PDF: 19 € per file (excl. VAT where applicable) — offered only when the fix removes at least one failed rule; the result page shows the veraPDF failed rules before → after before you pay. No account, VAT ID optional.

We run veraPDF, the open-source PDF/UA and PDF/A validator of the veraPDF Consortium, with its PDF/UA-1 (ISO 14289-1) profile. You see every failed rule with its clause, test number and description. Our automatic fix then repairs the document-level failures, and veraPDF checks the fixed file again — so before you pay you see exactly how many failed rules there were before and how many remain after.

What the automatic fix changes

The page content is not changed. Digitally signed and password-protected PDFs are not modified.

Every veraPDF PDF/UA-1 rule, its error message and whether the fix removes it: PDF/UA-1 rule reference.

What it does not fix

Missing tags (structure tree), untagged page content, reading order, alternative text for images, table and form structure, fonts that are not embedded, scanned pages without text. These need the authoring tool (export as tagged PDF) or manual remediation; the result page lists them as remaining. veraPDF checks the machine-verifiable PDF/UA-1 requirements; some requirements (for example whether alt text is meaningful) need a human check. We therefore never call a file “accessible” or “compliant” — the result is stated as veraPDF numbers.

Price

The check is free. The fixed file costs 19 € per file, excl. VAT, one-off, paid by card (Stripe Checkout) and downloaded right after payment. The offer is shown only when the fix removes at least one failed rule. VAT is added at checkout where applicable; a VAT ID is optional (with a VIES-valid EU VAT ID, companies outside Finland get the reverse charge). See Pricing, Terms and Refund Policy.

Your file

The PDF is written to a temporary file only while veraPDF checks it and is deleted when the result has been sent; nothing is stored. The request log keeps the file size, rule counts and duration only. See the Privacy Policy.
