Important limitation

This browser-only checker is a helpful screening tool, not a complete WCAG audit. It does not replace keyboard testing, contrast testing, screen-reader testing, manual review, or specialist accessibility testing for complex applications.

Fix the reported issues, then test the complete page with real content and assistive technology.

HTML accessibility checker FAQs

Is this HTML accessibility checker free?

Yes. The local checks run in your browser without an account or server upload. Optional AI suggestions send the HTML to Google Gemini.

Does it check a website URL?

No. Paste the HTML source because browsers restrict direct access to another website from a client-side tool.

Does passing these checks mean my page is fully accessible?

No. These are common structural checks. Full accessibility also requires manual, keyboard, contrast, and assistive-technology testing.
