HTML Accessibility Checker

Plain-language feedback on pasted HTML or a fetched public page—useful for authors and front-end learners before you ship or hand off to QA.

Important limitations

This is an educational tool, not legal advice and not a WCAG or ADA “compliance certificate.”
Automated checks find only a fraction of accessibility barriers. Keyboard flows, focus order, meaningful alt text quality, and most ARIA patterns still need human review and assistive-tech testing.
Paste HTML: your markup stays in the browser; it is not uploaded. Fetch from URL: your browser requests the page directly (public http(s) only; obvious local/private hosts blocked). Sites without CORS will refuse—then paste source or a saved fragment.
Contrast hints only look at inline colors, not stylesheets. URL fetch often fails on production sites due to browser security; paste HTML is the reliable path.

Public http(s) pages only. Local and private networks are blocked. Some sites block automated fetches—if so, use Paste HTML.
