Quick Tool Overview

The Image Alt Text Generator builds alt text from what an image shows and what role it plays, then checks it: under 125 characters, no "image of", no keyword stuffing, and empty rather than descriptive when the image is decorative. That last case is the most commonly missed and the most damaging.

About the Image Alt Text Generator

Alt text is not a caption and it is not a keyword slot. It is what someone hears instead of seeing the image, which means the right words depend entirely on why the image is on the page.

This walks through that: what the image shows, what role it plays — content, a link, a chart, or pure decoration — and any text visible inside it. From those it assembles alt text and checks it against the rules that matter: under 125 characters, no "image of", no keyword stuffing, and empty rather than descriptive when the image is decorative. That last one is the most commonly missed, and it is the difference between a clean screen-reader experience and a stream of noise.

Key features of the Image Alt Text Generator

Role-aware

Content, link, chart and decoration each need different alt text, and the tool asks rather than assuming.

Handles the decorative case

Produces alt="" for decoration, which is right and is what most generators get wrong.

Length check

Flags anything over 125 characters, where screen readers start truncating.

Catches bad habits

Warns about "image of", filename-style text and repeated keywords.

Shows the image while you write

Which is most of the job, and something a bulk generator cannot do.

How to use the Image Alt Text Generator

  1. 1

    Load the image

    Looking at it while writing is most of the job.

    Say what role it plays

    Content, a link, a chart, or decoration — each needs different alt text.

  3. 3

    Describe what matters

    What a sighted reader would take from it, not everything that is in it.

  4. 4

    Check and copy

    Length, phrasing and stuffing are checked, then the markup is ready.

Frequently asked questions

Under 125 characters. Some screen readers truncate around there, and anything longer usually means the description belongs in the page text instead.
