Type a short description above to generate alt text. This tool formats your words into accessible, well-structured alt text. It does not look at the image itself, so check that the wording matches what is actually shown.

Alt text is the written description a browser shows when an image fails to load and that screen readers read aloud to people who cannot see the image. Accessibility comes first: the goal is to give a blind or low-vision visitor the same information a sighted visitor gets from the picture. Search engines read the same attribute, so well-written alt text helps with SEO too, but if you write for accessibility first, the SEO benefit follows on its own.
Keep it concise. Aim for under about 125 characters, roughly one clear sentence, because some screen readers cut off longer descriptions. Be specific about what matters in the image rather than vague. Do not begin with "image of" or "picture of", since the screen reader already announces that it is an image. Include your keyword only when it genuinely describes the picture, and never repeat the same keyword across every image on the page, which reads as stuffing and can hurt you.
Two cases need special handling. Decorative images, such as background flourishes or spacer graphics that carry no information, should use an empty alt attribute (alt="") so assistive technology skips them cleanly. Functional images, like a magnifying-glass icon that runs a search, should describe the function ("Search") rather than the appearance, because that is what the user needs to know.
| Image | Bad alt text | Good alt text |
|---|---|---|
| Photo of a barista | image of coffee | Barista pouring latte art at a wooden cafe counter |
| Product shot | IMG_4821.jpg | Blue ceramic pour-over coffee dripper, front view |
| Company logo | logo logo brand | Rankite logo |
| Decorative divider | decorative line graphic line | (empty alt="") |
| Search icon button | magnifying glass picture | Search |
Clean alt text helps images surface in Google Images, gives context to the page they sit on, and keeps your site accessible, which is increasingly a ranking and legal consideration. It is one signal among many, though, and no amount of alt text fixes thin content or slow pages.
