Website accessibility checker: find WCAG issues in seconds

Our scanner fetches your page HTML and runs 16 automated checks based on WCAG 2.1 Level AA success criteria. Each check is weighted by its impact on real users - missing alt text and form labels affect more people than missing ARIA roles, so they carry more weight.

1. Scan your URL to get a scored report across the 16 WCAG checks.
2. Fix high-impact issues first - missing alt text, form labels, and low color contrast affect the most users.
3. Test with a keyboard - tab through the page and confirm every control is reachable and the focus order is logical.
4. Test with a screen reader (VoiceOver, NVDA) to catch issues automated tools can't.
5. Re-scan and document - publish an accessibility statement and re-test after changes.

Web accessibility isn't only good practice - in many places it's a legal requirement. In the US, the ADA has been applied to websites, and thousands of accessibility lawsuits are filed each year against businesses of every size, often triggered by automated scans of the exact issues this tool flags (missing alt text, unlabeled forms, poor contrast). In the EU, the European Accessibility Act sets requirements for many digital services. Beyond compliance, accessible sites reach the roughly 15% of people worldwide living with a disability and tend to be more usable for everyone - clearer structure, better contrast, and keyboard support help all users. This is general information, not legal advice; for compliance obligations, consult a qualified professional.

• Missing alt text - add concise, descriptive alt to meaningful images; use empty alt for decorative ones.
• Low color contrast - ensure text meets the 4.5:1 ratio (3:1 for large text). Check with our contrast checker.
• Unlabeled form fields - associate every input with a visible <label>.
• No keyboard access - make every interactive element reachable and operable with the keyboard.
• Missing page language - add lang="en" to the html element.
