Image Alt Text & Image SEO Checker

This tool lists the images of a page, flags missing alt text (accessibility and Google Images), measures file sizes, and spots images without width/height that make the layout jump.

Checks performed

Writing good alt text

Describe what the image shows and why it is there, in a short sentence. "Craftsman stitching a leather bag" beats "image1.jpg" or a list of keywords. Purely decorative images should have alt="" so screen readers skip them.

Image weight

Images are usually the heaviest part of a page. Resize to the displayed size, convert to WebP or AVIF, and lazy-load images below the fold.

FAQ

Is an empty alt="" an error?

No. It is the correct way to mark a decorative image. A missing alt attribute is the problem.
