TESTED & REVIEWED
WHY USE IT
See each detected issue with a line reference and a plain-language explanation of what needs attention.
Review image alternatives, form labels, heading order, link names, button names, iframe titles, table captions and duplicate IDs.
Catch frequent markup mistakes before completing keyboard, screen-reader, contrast and other manual accessibility tests.
HOW IT WORKS
Add a complete document or the component you want to review.
The browser inspects important elements and reports likely barriers.
Correct the findings, rerun the scan and finish with keyboard and assistive-technology testing.
COMMON QUESTIONS
No automated checker can prove full WCAG conformance. This tool finds common markup problems and should be followed by keyboard, screen-reader, zoom, motion and color-contrast testing.
An empty alt attribute can correctly hide a purely decorative image from assistive technology. The checker warns when alt is missing, not when it is deliberately empty.
