Alt text checker FAQ
What is alt text and why does it matter?
Alt text is a short written description of an image. Screen readers read it aloud so people who cannot see the image still understand it, and search engines use it to understand your visuals. Images with no alt attribute leave those visitors and crawlers with nothing.
Does an empty alt attribute count as missing?
No. A deliberate empty alt (alt="") tells assistive technology that an image is decorative and can be skipped, which is a valid choice. We only flag images that have no alt attribute at all, the same rule our full audit uses.
Do I need to sign up?
No sign-up and no email to run the scan. You will see every image missing alt text right away. Enter your email only if you want the complete report, including the other issues we found, sent to you.
How many pages does it check?
