Free Image Alt Text Checker
Enter a URL to find all images on the page that are missing alt text — a common accessibility and SEO issue.
How it works
This tool scans every image on your page and reports which ones are missing the alt attribute. Alt text is essential for accessibility — screen readers rely on it to describe images to visually impaired users.
Missing alt text also means search engines can't understand your images, which is a missed opportunity for image search traffic.
