Free website accessibility checker

AccessRadar finds common accessibility issues on any public page: missing alt text, empty links and buttons, form fields with no label, missing page language, title and heading problems, untitled iframes and more. Each issue comes with the element, the WCAG success criterion and a plain-English fix.

Automated checks find some, not all, accessibility issues (they catch only a portion of WCAG problems). This is not legal advice, not a legal assessment and not a certification.

• Linked image with no alt text (link reads as blank)
