Image Alt Text Generator

Alt text does two jobs at once: it's what a screen reader announces to a blind visitor, and it's the main signal Google Images has about what your picture shows. Most blogs get it wrong in the same three ways — dumping the target keyword into every image, starting with “image of”, or leaving it empty on images that carry real meaning.

Describe what's actually in the image and this tool assembles alt text that reads naturally, folds in your keyword only when it genuinely fits, and warns you about the classic mistakes: over-length text that screen readers truncate, redundant “picture of” prefixes, keyword stuffing, and missing context. It also outputs a complete img tag with width, height, and loading attributes so you avoid layout shift.

How to Use the Image Alt Text Generator

  1. 1Describe the image in plain words — what a person would see if they couldn't see it.
  2. 2Add the page's target keyword only if the image genuinely relates to it.
  3. 3Set the image filename and dimensions to build the full img tag.
  4. 4Mark it as decorative if the image adds no information — the tool will output an empty alt attribute as accessibility guidelines require.
  5. 5Copy the alt text or the whole tag, and read the warnings before publishing.

Frequently Asked Questions

How long should alt text be?
Under about 125 characters. Some screen readers cut off around that point, and anything longer usually means the detail belongs in a caption or the surrounding copy instead.
Should I put my keyword in every alt tag?
No. Keyword-stuffed alt text is an explicit Google spam signal and makes the page hostile to screen-reader users. Use the keyword in one or two images where it honestly describes what's shown, and describe the rest plainly.
Do decorative images need alt text?
They need an empty alt attribute, which tells screen readers to skip them. Omitting the attribute entirely is worse: some readers then announce the filename instead.
Should alt text start with “image of” or “photo of”?
No. Screen readers already announce that it's an image, so the prefix wastes the listener's time. Start with the subject: “Golden retriever puppy asleep on a blue rug”, not “Photo of a golden retriever…”.
