Alt text checker
Paste your page's HTML and see which images have missing, empty, redundant or file-name alt text — the four ways WCAG 1.1.1 most often gets broken. Nothing is uploaded; the parsing runs entirely in your browser.
Copy the page source (or just the part with images) and paste it here. Nothing is uploaded — the parsing happens entirely in your browser.

What this checks — and what it can't
This tool reads the markup you paste and flags the mechanical problems: an image with no alt attribute at all, an empty alt="" that might be hiding real content, alt text that's just the file name, or a redundant “image of…” prefix. What it cannot judge is whether a present, well-formed alt text actually describes the image well — that needs a human who can see it. A green result here means the alt text exists and is plausibly written, not that it's correct.
Pasting one page's HTML is a spot check. A real site has this problem across templates and CMS content at once — our free scanner crawls the live page for you, and if the fixes are bigger than one afternoon, these agencies do this for a living.
