HTML Accessibility Spot Check

Paste HTML source for a quick check of a few common accessibility issues. Your source stays in your browser; this tool does not submit it to a server.

Important: This is a limited spot check, not a WCAG audit or compliance certification. It cannot check visual contrast, keyboard behavior, rendered styles, or whether text alternatives are appropriate. Results require human review.

How to use

  1. Open your page, view its page source, and copy the HTML.
  2. Paste it above and select Check HTML.
  3. Review each finding and manually test with a keyboard and assistive technology.

This utility checks a small set of HTML patterns and can miss errors, particularly generated content and JavaScript-driven interfaces. Do not paste passwords or sensitive data.
