Image Alt Text Generator

Alt text is the short written description a screen reader announces and a search engine reads when an image can't be shown. Getting it right helps visually impaired visitors understand your page and gives Google extra context for image search. This image alt text generator turns a plain description of your image, a target keyword, and the surrounding page topic into several ready-to-use alt-text suggestions, all in your browser with zero AI cost.

Instead of staring at a blank attribute, paste in the subject of the photo (or even just the raw filename), tell it what the page is about, and the image alt text generator assembles natural, length-checked variations that read like a human wrote them. Each suggestion stays inside the recommended character range, weaves in your keyword without stuffing, and skips redundant phrases like "image of" that screen readers already announce.

Pick the variation you like, copy the finished <img> tag, and drop it straight into your HTML or CMS. It's a fast, free way to make every image both more accessible and more discoverable.

FAQ

How long should image alt text be?

Aim for roughly 60 to 125 characters. That's long enough to describe the image meaningfully but short enough that screen readers and search engines don't truncate it. This tool flags any suggestion that runs too long or too short so you can choose a balanced option.

Should I put my keyword in the alt text?

Yes, when it fits naturally. A keyword that genuinely describes the image gives search engines helpful context. Avoid forcing it or repeating it, keyword stuffing in alt attributes can look spammy and hurts accessibility. The generated suggestions place the keyword once, in a readable spot.

Do decorative images need alt text?

Purely decorative images (borders, spacers, background flourishes) should use an empty alt="" so screen readers skip them. Use descriptive alt text only for images that carry meaning or information. Want to track how your image-rich pages actually rank in local search? start free with ProMapRanker.
