Free website accessibility checker
Run a fast WCAG 2.2 accessibility scan on one public page. See the highest-risk automated findings, the checks that still need a person, and where to start fixing.
- Testing against the rendered page
- Technical risk and severity in one clear snapshot
- Explicit human-review boundary, never fake certification
Submit only a public URL you are authorized to test. We process the address to perform the requested check and never send it to website analytics.

First repair step
Useful automation
Catch the failures software can prove.
The checker renders the submitted page and applies the same normalized web-testing pipeline used by AccessPreflight projects. It is intentionally smaller than the authenticated workflow: one desktop page, one fixed WCAG 2.2 AA profile, and no evidence export.
- Names and labels
- Controls, buttons, links, and landmarks
- Visual contrast
- Machine-testable text and UI contrast
- Page structure
- Headings, landmarks, lists, and relationships
- Interaction signals
- Selected keyboard, focus, and ARIA failures
The honest boundary
A WCAG checker cannot decide everything.
Automated accessibility testing is valuable because it finds repeatable failures quickly. It becomes misleading when untested experience is presented as a pass. AccessPreflight keeps manual checks visible in every result.

Website checker FAQ
Know what the result means.
A useful accessibility report is precise about what ran, what failed, and what still needs human judgment.
What does the free website accessibility checker test?
It renders the submitted public page and checks machine-detectable conditions covered by the AccessPreflight WCAG 2.2 AA web profile, including accessible names, contrast, structure, and selected interaction risks.
Is this a WCAG compliance test or legal certification?
No. Automated testing can identify real technical failures, but it cannot determine full accessibility or legal compliance. The report keeps required human review visible instead of turning untested conditions into passes.
Does the checker scan my whole website?
No. The free check evaluates exactly one submitted public URL. Create a free account to organize more pages, documents, reports, and repeatable scanning workflows.
Does it support WCAG 2.2, ADA, EAA, and Section 508 work?
The free scan uses a WCAG 2.2 AA technical profile. WCAG findings can support broader ADA, European Accessibility Act, and Section 508 programs, but the scan does not make a jurisdiction-specific legal determination.
Can I check PDF and DOCX files?
You can use the free PDF accessibility checker for one PDF up to 10 MiB and 25 pages. DOCX checks and full document reports are available in a free Sandbox workspace.
Why are some report details locked?
The public checker is a fast technical preview. A free account unlocks the full workflow for normalized findings, selectors, evidence, complete remediation, exports, PDF, and DOCX scans.
