Paste your HTML code and every image is checked for missing, empty, too short or duplicate alt texts. Nothing is uploaded; everything runs in your browser.
This alt text checker analyzes every image in your HTML directly in the browser — your code never leaves your device. Paste the source of your page into the box, click Check Alt Texts, and the tool goes through each img tag in document order. It flags the alt text issues that hurt accessibility and SEO the most: a completely missing alt attribute, empty alt texts on images that are not decorative, descriptions that are too short to be useful or so long they get cut off, alt texts that just repeat the file name like image1.jpg, and the same alt text reused on several images. Descriptive, unique alt texts help screen reader users understand your images and give search engines the context they need to rank your page. No signup, no upload, no file limits — just paste, check, and fix.
