How to describe an image with AI

  1. 1

    Drop in a picture, choose one, or paste a screenshot.

  2. 2

    Choose brief or detailed, and add what to focus on if you like.

  3. 3

    Press Describe image.

  4. 4

    Copy the description and use it wherever you need it.

Brief or detailed?

Two lengths, for two kinds of job.

  • BriefOne or two sentences: the main subject, what's happening and where. Good for a quick summary or a file note.
  • DetailedA paragraph of 80 to 150 words: the subject, the setting, colours and light, how the picture is composed, and any words in it.

What an image description is good for

Anywhere words have to stand in for a picture.

Product listings and catalogues

Start a listing from what the photo actually shows: the shape, colour, material and setting. Add the facts only you know, like the size and the price.

Records, briefs and research

Describe photos for a report, a design brief, a mood board or an archive, so they can be searched and understood without opening each one.

Accessibility and social media

A detailed description helps with complex pictures such as charts or infographics. For a post, the free alt text generator writes something shorter, and the image caption generator turns the same photo into captions.

Questions, answered

How does the image description generator work?

Upload a picture and choose a length. AI looks at the picture and writes a factual description of what it shows. Add a note to tell it what to focus on.

What's the difference between an image description and alt text?

Alt text is short, usually one sentence, and is written for screen readers in place of a picture on a website or post. An image description can be as long as the job needs, and can cover everything in the picture.

Is the image description generator free?

Yes. It is free, with no login and no sign-up. To keep it free for everyone, each person can use it up to 30 times a day.

Will it identify people?

No. The generator never names or guesses who someone is. It describes what they're doing and wearing.

Is the description always right?

It's usually accurate, but AI can mistake small details. Read it through before you use it, especially for anything important.

What happens to my picture?

Your picture is shrunk in your browser and sent to OpenAI, whose AI writes the description. Posttyy doesn't save your picture or the description.
