Image Alt Text Generator
Describe any image for accessibility and SEO with on-device AI: short, medium or long, with three wordings to choose from. Create clear, descriptive alt text for any image in seconds.
What Is Image Alt Text?
Image alt text is the short written description added to a picture through its alt attribute, sometimes called the alt tag. Screen readers speak this text aloud, and search engines use it to understand what an image shows. It also appears in place of the picture when an image cannot load. The Image Alt Text Generator writes this description automatically: it reads a single uploaded image and drafts a clear line that explains the subject and scene. The result is ready to drop into the alt field of a web page, post, or product listing, with no manual wording.

Data Security
Every image stays on the device from start to finish. The picture is read and described locally inside the browser, so nothing is sent to a server and nothing is uploaded at any point. Only a one-time model file loads from a content network so the tool can run; after that first load, it caches for the rest of the session. No image is stored, logged, or kept once the tab is closed, which keeps personal and client work fully private.
Everything You Need To Know
No. The image is only read, never edited or downloaded. Nothing is added or altered in any way.
Yes. Each draft is a starting point; copy it, then adjust the wording to match the image's exact context.
A connection is needed only for the first load. After that, the tool keeps working even if the connection drops.
There is no strict limit, though very large images may take a little longer to process on the device.
Yes. Any standard raster image works, including photos, screenshots, graphics, and product shots.
Yes. Each length sets a new target, so switching to long produces a fuller description and refreshes the wordings shown.
