How it works & examples
How to write useful image alt text
This tool generates an AI-written description from an uploaded image. Use it as a starting point for the text alternative that communicates an image’s purpose to people who cannot see it.
How to use this tool
Upload a supported image, generate the description, then edit it for the page where the image appears. Include essential visible information and relevant text, and verify names, quantities, and details before publishing.
Example
For a product photo, “Blue ceramic mug with a curved handle” may be useful. For a chart, include the conclusion and provide the underlying values or a longer description nearby.
Understanding your result
An AI description cannot infer every page’s context. Decorative images generally need an empty alt attribute, while linked images may need text describing the link’s action. Avoid keyword stuffing and do not treat generated alt text as automatic accessibility compliance.
