Image Alt Audit Pro

Scan your HTML for images missing alt text, empty alts and oversized filenames — with an SEO score.

How to use

Paste your HTML and run the audit. Each image is graded and you get an overall alt-health score.

Is empty alt ever OK?

Yes — decorative images should have alt='' so screen readers skip them.

What hurts the score?

Missing alt attributes, keyword-stuffed alts over 125 characters, and generic filenames.
