AI Image Alt Text Generator

How it works

The image goes to a vision model running on Cloudflare Workers AI, along with any context you provide and the instruction to stay under 125 characters. You get three options that describe the same image from different angles, so you can pick the wording that fits where the image sits on the page. Nothing is stored, and no page of yours is crawled — this is a writing tool, not an audit.

Alt text is the alt attribute of an <img>. It is read aloud by screen readers, and it is the only thing a search engine has to go on when it cannot see the image itself, which is why "IMG_2481.jpg" tells it nothing and "black running shoes with a white sole on a track" tells it plenty. Keep it a short description of what is in the image rather than a list of keywords: repeated keyword stuffing in alt text is treated as spam, not as relevance.

A decorative image is the exception: if it adds nothing to the meaning of the page, it should have an empty alt="" so screen readers skip it entirely. For the measured view of a page you already have, run the free SEO audit.
