Alt Attribute Checker

Analyze <img> tags for missing, empty, or low-quality alt attributes — fully client-side.

Paste HTML or Load File

Check all <img> tags for alt attribute issues (missing, empty, or suspicious).


      Tip: Decorative images should use empty alt (alt=""); informative images should have concise, meaningful alt text.
