A11yAudit: WCAG Contrast & Compliance Checker

Find WCAG 2.2 AA accessibility issues on any page. Exact CSS selectors, fix guidance, and exportable compliance reports.

Run a WCAG 2.2 Level AA accessibility audit on any page with one click. A11yAudit reads the page you are viewing and reports every barrier that automated checking can detect — contrast failures, missing labels, untitled buttons and frames, broken heading order, viewport that disables zoom, and more. Every finding comes with the exact CSS selector of the problem element. Click "Locate" and the element is highlighted in place. The fix guidance is one click away. Two export formats: • CSV — for engineers writing tickets. • HTML report — a client-ready document you can open, print to PDF, and attach to deliverables. Includes a summary, severity counts, every finding with its selector, and a built-in legal scope note reminding the recipient that automated checks catch roughly a third of WCAG criteria. How it works: 1. Click the extension icon on any page. 2. The right-hand panel opens with the results in a few seconds. 3. Address findings by severity, export your report, hand it to the client. Coverage: • Color contrast (WCAG 1.4.3 / 1.4.11) • Image alternate text (1.1.1) • Form field labels (4.1.2) • Accessible link and button names (4.1.2) • Page language (3.1.1) • Document title (2.4.2) • Heading structure (1.3.1, best practice) • Iframe titles (4.1.2) • Viewport zoom lockout (1.4.4) Powered by axe-core 4.10.2 with a built-in fallback for pages that restrict script evaluation.
