Image Alt Text Auditor
Paste your HTML and get alt-text coverage: how many images have alt, which are empty, and which are overly long — with why it matters.
What this tool checks
Empty alt is sometimes right
A purely decorative image should have alt="" so assistive tech skips it. We flag empties so you can confirm they're intentional.

FAQ
Common questions
How long should alt text be?+
Concise and descriptive — under ~125 characters. Describe the image's purpose, not every detail, and don't keyword-stuff.
Does alt text help SEO?+
Yes — it's how image search understands a picture, and it's an accessibility requirement. Both matter.
