Fetch a page and list every image with missing, empty or long alt text.
An image alt checker loads a page and reports how many images have alt text, which are missing it and which have very long values. Fixing missing alt text helps accessibility and image search.
This tool fetches the address you enter once, from our server, and reports what a crawler would receive. The URL is not stored; only a short-lived rate-limit counter is kept. Results show the page at the moment of the check and can differ from what a logged-in browser or a bot with different headers sees.
Reads the real page at the moment you run it, with every redirect followed and shown.
Each finding says what it means and what to do next, not just a raw value.
Copy the output straight into your CMS, spreadsheet, ticket or client report.
Free, with no signup. Fair-use limits keep the tool fast for everyone.

Fix missing values in your CMS.
The report counts images with alt text, flags those missing it and points out very long values. Start with images that carry meaning, such as product photos, charts and linked images, and write short, specific descriptions. Mark decorative images with an empty alt attribute so screen readers skip them. Shorten overly long alt text and move extended explanations into the visible copy. Check that linked images have alt text describing the link destination, since the image is the only label. After updating, run the check again to confirm the counts changed. Prioritise templates, because fixing the logo, icons or repeated components can clear many flagged instances across the site at once.
Do not fill empty alt fields with filler to reduce the missing count, such as repeating the page title on every image. That adds noise for screen reader users. Another mistake is treating a missing attribute and an empty attribute as the same: an empty alt is a deliberate choice for decorative images, while a missing one leaves the reader guessing. Avoid keyword stuffing and descriptions such as "image1". Remember that the check reads the HTML returned by the server, so images loaded later by scripts or set as CSS backgrounds may not be listed. Finally, check lazy-loaded images, whose real source and alt may be set by a plugin.
