Image Alt Tag Checker
Scans every image on the page for a missing alt attribute.
What this tool checks
Images have alt text
Checks how many <img> elements are missing an alt attribute. An explicit empty alt="" (decorative) is allowed.
Why it matters: Alt text makes images accessible to screen readers and gives search engines context for image search. A missing alt attribute is different from an intentionally empty one.
If it fails: Add descriptive alt text to meaningful images; use alt="" only for purely decorative images.
