Alt Text Generator

Free alt text generator: upload a JPEG, PNG or WebP up to 5 MB or paste an image link — the AI describes it in three versions (short, descriptive, tailored to your page) in 15 languages and tells you if it looks decorative (then use an empty alt). The image is not stored. 15 generations a day without an account. Check that the description is accurate before publishing.

The file is larger than 5 MB. Resize it or save it as JPEG/WebP.

The image is processed in memory and not saved on our server; it is downscaled to 1024 px for the AI. To make repeat requests free, we keep only the generated text for 24 hours, keyed by a fingerprint of the image.

Generations today: 0 of 15. Repeating the same request within 24 hours does not use the limit.

Good alt text in one minute

  • Describe what matters on this page, not everything in the picture: the same photo can need different alt text on a product page and in an article.
  • Decorative images (backgrounds, dividers, icons next to a text label) get an empty alt="", not a missing attribute — without alt, a screen reader may read out the file name.
  • Linked images and buttons: the alt describes the action or destination (“Download the price list PDF”), not the look.
  • Skip “image of…” / “photo of…” and never stuff keywords: Google explicitly calls keyword-stuffed alt attributes spammy. Around 125 characters is a common guideline, not a hard limit.
  • To find images missing alt text on a live page, use the image SEO checker. Image SEO checker →

Free AI Alt Text Generator for Images

Alt text is the image description in the alt attribute: screen readers read it to blind and low-vision users, Google uses it to understand the image, and it shows when the image fails to load. Upload a JPEG, PNG or WebP up to 5 MB or paste an image link, and a vision model suggests three versions — short, descriptive and tailored to your page — in one of 15 languages. If the image looks decorative, we tell you it needs an empty alt, and if it contains text, we show it. The image is processed in memory and never stored. Check the description before publishing: the AI can get details wrong.
