For developers and designers

Find and fix accessibility issues in your HTML

The Accessibility Checker reviews pasted HTML, JSX or a component against WCAG 2.2: missing labels and alt text, heading order, keyboard and focus problems, misused ARIA and colour-contrast risks. Each issue is ranked by severity, linked to its WCAG success criterion and comes with corrected code.

Why accessibility matters

One in six people lives with a disability. If they can't use your site with a keyboard, a screen reader or zoomed text, they leave. Accessibility is also a legal requirement in many countries and for public-sector and enterprise work.

Accessible sites are better for everyone: clear labels, logical headings and real buttons also help SEO, voice assistants and people on small screens.

The most common problems

Images without alt text, form fields without labels, clickable divs instead of buttons, skipped heading levels, missing focus styles and low-contrast text. Most are quick fixes once you know where they are.

What an automated check can't do

A code review finds many issues but not all. Contrast depends on the final CSS, and real usability needs testing with a keyboard and a screen reader such as NVDA or VoiceOver. The checker ends with the manual checks that matter for your code.

Questions

Frequently asked

What is WCAG 2.2?+

The Web Content Accessibility Guidelines, version 2.2, from the W3C. It's the standard most accessibility laws and audits refer to, with levels A, AA and AAA. Most sites aim for AA.

Can it check colour contrast?+

Only where colours appear in the pasted code, and it flags them as risks. Confirm contrast with the final styles using a contrast checker or your browser's dev tools.

Does it replace a full accessibility audit?+

No. It catches common code-level issues fast. A full audit adds manual keyboard and screen reader testing across the whole site.

Does it work with React and Vue?+

Yes. Choose your code type and the fixes come back in the same syntax, using className, htmlFor and other framework conventions.

Is this tool free?+

Yes. Every tool on this site is free with no sign-up. Each visitor gets 10 runs per tool per day, which keeps the tools fast and available for everyone.

Is what I paste saved or shared?+

No. Your input is sent to the AI model (Claude by Anthropic) only to generate your result, and it is not stored on this site. Still, do not paste passwords, financial details or anything confidential.
