Check PDF accessibility against WCAG & PDF/UA for free
WebYes offers a free, browser-based PDF accessibility checker that scans PDF documents against WCAG (Level A and AA) and PDF/UA (ISO 14289) machine-verifiable criteria. It lists every issue ranked by severity — from critical to minor — with plain-language explanations and fix guidance mapped to the relevant WCAG or PDF/UA rule, and pinpoints each problem element directly on the PDF. No sign-up, email, or software installation is required, and uploaded PDFs are not stored. It is aimed at teams and individuals who need to address accessibility obligations under the ADA, Section 508, and the European Accessibility Act (EAA). Beyond the free checker, WebYes sells expert PDF audits, PDF remediation services, and a broader WebYes Suite covering website accessibility, SEO, performance, quality, and uptime monitoring.
Checks every machine-verifiable success criterion of WCAG (Levels A and AA) and every machine-verifiable test in PDF/UA (ISO 14289).
Every issue is ranked from critical to minor, with severity filtering, so the most important fixes can be prioritised.
Clicking any issue jumps straight to the problem element, highlighted on the PDF itself.
Each issue includes a plain-language explanation of what is wrong and how to fix it, mapped to the related WCAG or PDF/UA rule.
Verifies reading order, heading level nesting, list structure, and whether tables have associated headers.
Checks font embedding and Unicode mapping, image alt text, document language, and presence of a title and bookmarks.
Tests text contrast against WCAG minimums, form field labels and tags, link tagging and descriptions, and tab order.
Fully online with no sign-up, no email required, uploaded files not stored, and no software to install — upload a PDF or paste a public link.
Upload a PDF file or paste a public link to it — the tool runs entirely in your browser with nothing to download or install.
The checker runs all machine-verifiable WCAG (A and AA) success criteria and PDF/UA (ISO 14289) tests on the document.
Results are grouped into issues, needs-review items, and manual checks, with each issue listed worst-first and filterable by severity.
Each issue explains what is wrong and how to fix it; you or your team apply the fixes, or hand the document to WebYes's paid remediation service.
The PDF accessibility checker itself is free to use with no sign-up. The broader WebYes Suite (website accessibility, SEO, performance, quality, and uptime) is priced at Free ($0), Pro ($59/month), Enterprise ($99/month), and a custom Scale-up plan; paid plans come with a 3-day trial and can be cancelled anytime. Local taxes (VAT, GST, etc.) are charged in addition to listed prices.

Yes, completely free. No sign-up, no email, and no files are stored.
It is a fully online tool with no software to download or install. You upload a PDF or paste a public link and check it right in your browser.
Upload your PDF or paste a public link. The checker scans it against WCAG and PDF/UA, then lists every issue by severity with guidance on how to fix each one.
Every machine-verifiable success criterion of WCAG (Level A and AA), and every machine-verifiable test in PDF/UA (ISO 14289).
Yes. It checks against the WCAG and PDF/UA standards that underpin the ADA and Section 508 and flags issues that affect compliance, but some checks still need to be done manually to determine whether a PDF is fully compliant.
No. A clean scan means your PDF passed every machine-verifiable check. Some checks can only be done manually, and those must also pass before a PDF is considered fully compliant. WebYes's expert audit covers that manual testing.
It finds and explains them, with plain-language descriptions and fix guidance. You or your team apply the fixes in your document; alternatively, WebYes offers full PDF remediation as a paid service.
