Frequently Asked Questions

Find answers to common questions about this tool.

What does the inspector check in image alt attributes?

It checks for missing alt text, empty alt attributes, overly long alt text (>125 characters), keyword stuffing, and file name used as alt text.

Does the tool check images inside links?

Yes. Images wrapped in <a> tags are flagged, since alt text for linked images should describe the link destination, not the image content.

Can I analyze alt text from a URL?

No. Paste the HTML content directly. The tool parses all <img> tags and their attributes from the pasted HTML.

What is the recommended alt text length?

125 characters or less. Screen readers cut off alt text at approximately 125 characters. Longer descriptions should use the longdesc attribute or aria-describedby.

Does the tool detect decorative images that should have empty alt?

No. It flags all images with empty alt text but notes that decorative images should use alt="" (empty) rather than having no alt attribute at all.
