Free Alt Tag Checker
An alt tag checker scans your website's images for missing, empty, or low-quality alt attributes. AltTagFix runs a fast technical scan so you can prioritize fixes before they affect accessibility or image SEO.
What an alt tag checker looks for
Common issues include missing alt attributes, placeholder text like "image" or "photo", filenames used as alt text, and alt strings that are too short to describe the image.
How AltTagFix works
Enter your site URL to crawl up to five pages. You see a preview of issues immediately. Enter your email on the results page to unlock the full list, CSV/PDF export, AI alt suggestions, and an optional full-site audit (up to 20 pages).
Who should use this
Marketing teams, ecommerce managers, and developers who need a quick inventory of image alt problems — without installing browser extensions on every page.
Is AltTagFix an alt tag checker?

Do I need to install anything?
No. Run the scan in your browser. No account is required for the free preview.
