Describe any image with AI Image Describer

Drop or paste a photo. This image describer turns it into prompt text for ChatGPT, Gemini, or any AI image generator — no new tab, no signup. Hoard references without writing a paragraph about each one.

image to prompt

Describe this image

Upload a photo, copy the prompt, move on. Or add the extension for when you're mid-scroll on someone else's site.

Right tool, wrong tool

You have a reference and need words for a generator — that's the job. You need WCAG alt text, product listing copy, or every label on a screenshot spelled perfectly — pick a different tool.

Don't trust it blindly

  • Faces, medical scenes, IDs: names and details are guesses until you verify them.
  • Tiny or stylized text gets misread. Check your own numbers and logos.
  • It may invent lighting or style that wasn't in the frame. Edit the prompt before you generate.

How it works

Upload on this page, or grab the Chrome extension when you're already browsing. Same image-to-prompt job — two doors in.

Example photo for turning into a prompt

prompt

You know the shot. You don't know the sentence. Upload it — get subjects, light, and layout as a prompt for this scene. Paste into ChatGPT, Gemini, Nano Banana, or whatever you're running today.

  1. 01

    Drop, paste, or pick a JPG, PNG, or WebP (up to 10 MB).

  2. 02

    Copy the prompt. It lives in this browser until you clear site data.

  3. 03

    Want it in-flow? Pin the extension and right-click any photo to describe this photo on the spot.

Before you upload

Image-to-prompt here — not a caption mill.

What do I get if I ask it to describe this image?
Prompt-ready text from the pixels you sent: subjects, layout, lighting, style. Not a blog caption. Not alt text.
Will this work as picture-to-prompt writing for ChatGPT or Gemini?
Yes — one image at a time. Skim the output, tweak a line or two, paste. Same flow for Nano Banana or any AI image generator.
Do I need an account?
No email, no card. There's a daily free cap, shared with the Chrome extension on the same API.
Where do my prompts go?
This browser, this device. Clear site data and they're gone. We don't host a gallery for you.
Which file types?
JPG, PNG, WebP — up to 10 MB.
Can I use this for accessibility alt text?
Don't ship it as WCAG alt text without a human edit. This is for generator prompts.
How is the website different from the extension?
This page is drag-and-drop upload. The extension adds toolbar + right-click on any site. Same engine underneath.
How to describe an image for AI generators?
Upload the reference here, or hit the extension on whatever page you're on. You'll see how prompts are structured — handy if you're learning how to prompt image generators and tired of staring at a blank box.
Is this an AI image analyzer?
No — it's an image describer built for prompts, not a full scene labeler or document reader. Need an audit of every object? Wrong tool. Need words to recreate a look? Right one.
