What this tool can catch
The tool looks at img elements and classifies common patterns that often need review, including missing alt attributes, empty alt text, linked images without useful names, generic labels, repeated descriptions, likely decorative images, and filename-style alt text.
What still needs human review
It cannot decide whether a description is useful for the page purpose. A human still needs to review important images, charts, linked images, icons, and decorative images in context.
When to use this
Use it during content entry, before launching landing pages, after image-heavy page updates, or before handing a page to an accessibility reviewer.
Next: see alt text examples, print the alt text review checklist, try the main checker, or use this with the Canadian checklist.
