Frequently asked questions

Why does alt text matter?

Alt text is what screen readers announce and what search engines index for image search. Images that convey information need a short description; missing alt text is one of the most common accessibility failures.

Is empty alt text always a problem?

No — alt="" is the correct markup for purely decorative images, telling assistive technology to skip them. The problem is a missing alt attribute, which leaves screen readers to guess. This tool reports the two cases separately.

Why does an image show no src?

Many sites lazy-load images, keeping the real URL in data-src until JavaScript runs. This tool reads the server-rendered HTML and shows common lazy-load attributes where it can; the browser engine (free on sign-up) sees the fully loaded page.
