Image alt text checker
Find images without alt attributes in pasted HTML.
Templates and calculations run locally in your browser. No generative AI or paid API is used. Review results before use.
Check the page your visitors receive
Paste page HTML into the form. The checker reads the markup without executing its scripts. A page that adds headings or images with JavaScript may need its rendered HTML copied from browser developer tools.
A practical example
A product photograph needs a helpful description of the product. An ornamental divider can use alt="" so assistive technology can skip it.
What this tool cannot tell you
Decorative images can use an empty alt attribute. Meaningful images need useful descriptions based on their purpose.
