What this tool inspects

The checker inventories image elements in the fetched HTML. It lists source URLs, alt values, width/height declarations and loading attributes for up to 100 rows. Counts distinguish a missing alt attribute from an empty one. That difference matters when deciding whether an image is informative, decorative, duplicated by nearby text or acting as an interactive control.

How to read the result

Describe informative images according to their role on the page. Empty alt may be appropriate for decoration, so those entries are marked for verification rather than automatically failed. Missing width and height are a layout review cue; CSS may reserve space another way. Check the actual mobile layout and the image’s context before making a template-level change.

Where a manual check still matters

The checker does not download images, measure file size, inspect CSS backgrounds or render the page. It cannot determine image meaning or certify accessibility. A present alt attribute can still be unhelpful, and a responsive CSS layout can be stable without element dimensions. Use this inventory to choose the next human review, not to replace it.

Keep useful evidence

Successful checks save a snapshot to your browser workspace. Run the same tool on the same final URL again to compare check statuses with the prior saved result. Export CSV or JSON to keep a file, or print the result as a PDF. Browser data stays on this device and does not run automatic scans.

Common questions

Is empty alt always a problem?

No. Decorative images may correctly use alt="". Review the image in context before deciding whether a description is needed.

Is this a complete website audit?

This tool answers one focused question on a bounded public response. The launch audit combines 40 checks, with a free top-three preview and paid full reports.

Does this change my website?

No. These checks fetch public information and return evidence. You decide whether to change the site and verify the result after deployment.
