WCAG Checker

v1.1.0

Audit HTML against WCAG 2.2 success criteria.

Runs automated WCAG 2.1 accessibility checks on HTML content or a URL — tests for colour contrast, missing alt text, form label associations, keyboard focus indicators, skip links, and document language against Level A and AA criteria.

How to use
  • →Enter a URL or paste HTML markup to start the automated audit.
  • →Review findings grouped by WCAG principle: Perceivable, Operable, Understandable, Robust.
  • →Click any issue to see the failing element, the violated criterion (e.g. 1.4.3 Contrast), and a fix suggestion.
  • →Aim to resolve all Level A failures first, then Level AA — Level AAA items are advisory.
