Validate any PDF against WCAG 2.1 AA or strict PDF/UA-1. Every finding cites the exact ISO clause. Every report carries the file's SHA-256 fingerprint — evidence that holds up in an audit.

When the auditor, the regulator, or the lawsuit arrives, "we ran a checker and it looked fine" is not a defence. You need to prove which file was checked, against which standard, and exactly what was found.
A green icon in a desktop tool. No citation of which rule, no record of which file version, no way to reproduce the result six months later when the document has been revised twice and the auditor wants proof.
Every finding cites the exact ISO 14289-1 clause and test plus the Matterhorn checkpoint, with locations down to the page and text snippet — and renders in English or French from the same stored validation.
Drop a file, point at a URL, or call the API. Every failure is filed under the WCAG success criterion it breaks. Then let schedules re-validate your documents and alert you the day something regresses.
Validate single files or batches up to 200 MB, or give the validator a public URL and it fetches the document itself. Choose the WCAG 2.1 AA profile or the strict PDF/UA-1 rule set per validation.
Failures are grouped under the WCAG success criterion they break, with severity, occurrence counts, and locations — structure path, page number, PDF object, and a text snippet — so your remediation team goes straight to the problem.
Track whole web domains — free PDF discovery finds every document on a site. Group documents, watch the 90-day pass/fail trend, and schedule re-validation with regression alerts.
Built by the team behind the PDFUA.io generation engine — the same rule knowledge that creates compliant documents, pointed at verifying anyone's.
WCAG 2.1 AA for the regulations that cite it — ADA Title II, AODA, ACA — or the full, strict PDF/UA-1 rule set. A document can pass WCAG AA and still fail PDF/UA-1; you choose the bar per validation.
WCAG 2.1 AA · ISO 14289-1Verdict, errors and warnings, engine version, and the file's SHA-256 fingerprint — proof of exactly which bytes were validated. Reports are stored as evidence and re-render any time.
SHA-256 · stored evidenceEvery finding points at the structure path, page, and PDF object, with a short text snippet so remediators can find the exact spot. A privacy toggle omits snippets for confidential documents.
structure paths · snippetsSee accessibility per web domain: how many PDFs, how many passing, when each was last checked. Free PDF discovery crawls robots.txt, sitemaps, and pages to find every document on a site.
free PDF discoveryOrganize documents into groups — a site section, a remediation project, a client — and watch the 90-day pass/fail trend improve run over run. Re-validations update, never duplicate.
90-day trendDaily, weekly, or monthly re-validation of a group's URL documents. Alerts on regressions, fetch failures, and exhausted credits. Unchanged files are detected and not re-charged.
regression alertsEverything the app does is available over HTTP with an API key — validate from CI pipelines, document-management systems, or your own apps, and pull the JSON or HTML report back out.

Kick the tires on real documents. No card, no trial clock.
For one site and its audit binder.
For a team keeping one document estate honest.
For agencies and large estates under active deadlines.
Run the validator inside your network: a stateless validation API container that stores nothing (air-gap friendly), or the full self-hosted monitoring appliance with groups, schedules, and domain scanning. Reseller programs for accessibility agencies. Custom retention and credit pools.
Prices in USD. One credit per started 100 pages; an aborted validation charges one credit. Scheduled re-validation of an unchanged document — same SHA-256 fingerprint — costs nothing.
