Review HTML accessibility issues

Paste a page or a snippet. The checker renders it in a sandboxed frame, runs the axe-core rules and lists each problem with the affected element, the WCAG criteria and a suggested fix.

Paste HTML (a full page or a fragment).
Run the check; issues are grouped by impact.
Each issue shows the element, the rule and a suggested fix.

Supported formats and limits

Input	HTML
Output	Issue list (JSON/CSV)
Engine	axe-core running inside a sandboxed frame

Limitations

Automated checks find only part of accessibility problems; keyboard and screen-reader testing are still needed.
Passing this check does not mean a page is WCAG compliant.

Questions

Does a clean result mean my page meets WCAG?

No. Automated rules find only part of accessibility problems. Keyboard use, focus order, screen-reader output and meaning still need manual testing. Some results are marked Needs review because a rule cannot decide on its own.

Is my HTML uploaded?

No. The HTML is rendered and checked in a sandboxed frame in your browser, and the axe-core script is served from this site. Scripts and handlers in your HTML cannot reach this page.
