# Alt Text Checker Paste HTML and audit every image for accessibility. Each `` is checked for a missing, empty or low-quality `alt` attribute — the first thing a screen reader relies on — with a plain-language hint on how to fix it. Nothing is uploaded. ### How it works Your HTML is parsed locally with the browser's own `DOMParser`. Every image is inspected against WCAG 1.1.1: a **missing** `alt` attribute fails outright (a screen reader may read out the file path); an **empty** `alt=""` is correct only for purely decorative images; and alt text that just repeats the file name, or says "image"/"photo", is flagged as low-quality because it adds nothing a screen reader doesn't already announce. Descriptive alt text passes. A summary tallies good, needs-review and failing images. --- *Source: [ocxly.com/alt-text-checker.html](https://ocxly.com/alt-text-checker.html) — OCXLY, free 100% client-side privacy-first tools.
