SEO DESK
Parse supplied HTML, list all img elements, and report each alt attribute as present, missing, or empty, with the element's src and a snippet of the surrounding text.
WHAT THIS DOES
Runs entirely in your browser.
/tools/image-alt-checkerimage-alt-checkerv4.0.0LOCAL · LOCAL RUNIMPLEMENTED — This workbench is functional in the current release.Presets for this workbench
No preset yet. A preset stores the values in this form — never the result — and only for workbenches that run entirely in your browser.
Collections
Saved on this device only. Turn on sync to carry them to another device.
BATCH / ONE VALUE PER LINE
Up to 200 lines, one at a time, in this browser. Each line takes the place of html and everything else stays as you set it. Nothing is uploaded, and the row limit is not exceeded silently.
METHOD / LOCAL RUN
Detached DOMParser reads the HTML; the workbench iterates img elements and reports alt presence.
Boundary: Markup analysis only. Does not judge whether an alt is meaningful.
The calculation or transformation runs in your browser using the values entered above. No input is sent to UtilityForge for this tool.

FAQ
No. The image alt checker runs entirely in the browser.
No. These are local helpers for common artifacts. Production SEO still requires analytics, search-console data, and human review.
The workbench states the exact method behind every result — the formula or procedure this page runs — so you can verify the computation instead of trusting a black box.
No. This workbench runs in the page: HTML are read by the code your browser already downloaded, and UtilityForge receives neither the values nor the result.
Yes, and it is enforced rather than advertised: HTML (100,000 characters). The limit is a browser input limit on a tool that runs on this device, so nothing is truncated after being sent anywhere.
Markup analysis only. Does not judge whether an alt is meaningful.
