Give every image words

Alt text is the written description of an image that screen readers announce and search engines read. This tool suggests descriptive alt text for your images, helping you fill the attribute that is so often left empty, which matters for both accessibility and image search.

What good alt text actually says

Alt text describes what the image conveys in its context, concisely and specifically. A photo of a product should name the product; a chart should state its point; a decorative flourish needs no alt at all and should have an empty attribute so screen readers skip it. The common failures are an empty alt on a meaningful image, a filename left in as alt, or a keyword-stuffed description that helps nobody. Good alt text reads naturally as a description a person would give.

Two audiences, one attribute

Alt text serves a blind visitor who cannot see the image and a search engine that cannot either, and both are served by the same honest description. Treat the suggestions as a starting point to refine with the specific detail only you know about the image. The tool runs in your browser to help you draft the descriptions faster.

Frequently Asked Questions

What is alt text?

A written description of an image that screen readers announce to blind users and search engines read to understand the image. It lives in the image’s alt attribute.

What makes good alt text?

A concise, specific description of what the image conveys in context, reading naturally as a person would describe it, rather than a filename or a list of keywords.

Should decorative images have alt text?

No. Purely decorative images should have an empty alt attribute so screen readers skip them rather than announcing meaningless descriptions.

Does alt text help SEO?

Yes. It is how search engines understand an image, which supports image search rankings, and it improves accessibility at the same time.

Are the suggestions final?

They are a starting point. Refine them with the specific detail only you know about the image, since context matters.
