Image alt text checker
Every image,
Every image,
described.
Paste your page HTML and instantly see which images have good alt text, which are empty or duplicated, and which are missing it entirely — for accessibility and image search.
Paste your page HTML (or just the <img> tags). View source with Ctrl+U, copy, and paste.
This checks the alt attributes in the HTML you paste, entirely in your browser. It flags missing, empty, and duplicated alt text; whether an empty alt is correct depends on whether the image is decorative.
