Image Alt Text Checker
Paste HTML, find every image missing alt text, with context. Everything runs locally in your browser, nothing is uploaded.
About this tool
Missing alt text is the most common accessibility failure on the web. Find yours in one paste.
Why free, and what happens next
Tools like this one are how this desk stays findable: useful first, commercial when you are ready. When a tool surfaces a problem you would rather have fixed than diagnosed, start a project or run the cost calculator first. Everything runs client-side: your data never leaves this page.
