Accessibility Scan

Scan pasted HTML or a live URL for common WCAG and page accessibility issues.

Scan Input

URL fetching now uses the ZipTools server, so most public pages should load without browser CORS issues. If a site blocks bots, you can still paste HTML manually.

About the Accessibility Scan

  

    The Accessibility Scan audits a page for common WCAG-adjacent issues such as missing alt text, unlabeled form controls, vague links, duplicate IDs and broken heading structure. It runs entirely in your browser using a parsed DOM, which makes it fast, private and useful for quick one-page audits before deeper manual testing.

Frequently Asked Questions

  


    

      Does this scan an entire website?
      
This version is a page-by-page scanner. It is designed for quick audits of a single HTML document, either pasted directly or fetched from a CORS-enabled URL. A full crawler would need a more advanced backend or browser extension style architecture.

    


    

      Does passing this tool mean the page is WCAG compliant?
      
No. This catches common structural problems, but full accessibility evaluation also needs keyboard testing, focus management checks, color contrast analysis, screen reader review, motion considerations and human judgment.

    


    

      Why might URL fetching still fail for some sites?
      
The scanner now fetches pages server-side, which avoids normal browser CORS restrictions. Some websites still block automated fetches, require JavaScript rendering, or serve challenge pages instead of raw HTML. In those cases, paste the HTML directly for a reliable scan.
