Free AI Image to Prompt Generator
Every image has a spec. We read it back to you.
Upload a photo, paste an image URL, or drop in a screenshot and this free image to prompt generator gives back a structured prompt — subject, style, lighting, palette, composition, and your image’s exact aspect ratio — ready to paste into Midjourney, Stable Diffusion, or DALL·E.
Sample readout
lone mountain summit at dusk, painterly digital illustration, warm rim lighting from a low sun, palette of indigo, amber, and rose, rule-of-thirds composition, quiet contemplative mood, ultra-detailed, 8k --ar 3:2

Kickstart your creation
Two ways to get from image to prompt.
Let AI write the prompt for you
Upload a file or paste a link — either way, a vision model reads the image and writes back one structured prompt: subject, style, palette, lighting, composition, and quality tags, quoting any on-image text verbatim instead of guessing at it.
Try it now →Built to reproduce, not just describe
Every generated prompt carries your source image's exact aspect ratio, with a Midjourney --ar tag included automatically — so pasting it into another generator gives back an image shaped like the one you started with, not a random crop.

01
Upload or paste a link
Drop in a JPG, PNG, or WEBP up to 5MB — a photo, painting, render, or screenshot — or paste a link to any image on the web.
02
Analyze
A vision model reads the subject, style, lighting, palette, composition, and mood, and transcribes any visible text.
03
Prompt
Copy the finished prompt — with your image's exact aspect ratio built in — straight into Midjourney, Stable Diffusion, or DALL·E.
Prompt engineering, reversed
What is an image to prompt tool?
An image to prompt tool reads a picture the way a prompt engineer would — subject, style, palette, lighting, and composition — and writes that reading back out as text. Instead of guessing at the prompt behind a reference image, or typing out your own description by hand, you upload the image and an AI prompt generator turns it into a structured, ready-to-use prompt in seconds. It’s the fastest way to reverse-engineer a look, match a style across a series, or turn a moodboard photo into a prompt Midjourney, Stable Diffusion, or DALL·E can build on.
One image, every prompt format
Built for Midjourney, Stable Diffusion, and DALL·E.
Midjourney prompts
Get a descriptive prompt you can drop straight into /imagine, then layer on your own --ar and --v parameters.
Stable Diffusion prompts
The subject, style, and lighting breakdown reads cleanly as weighted tags for Automatic1111, ComfyUI, or any Stable Diffusion front end.
DALL·E prompts
DALL·E favors plain-language sentences over tags — the generated prompt is written as one, so it works as-is.
Questions
Frequently asked.
What is an AI image to prompt generator?
It's a tool that reads an image — subject, art style, color palette, lighting, and composition — and writes that reading back out as a text prompt, so you can recreate or riff on the look in Midjourney, Stable Diffusion, or DALL·E instead of describing it from scratch.
Is Image To Prompt free to use?
Yes — try it without an account for 2 free generations, then sign up for 5 free generations every month at no cost. Need more? Pro is unlimited. See /pricing for details.
Can I use an image URL instead of uploading a file?
Yes — switch to "Paste a link" in the generator and drop in any public image URL. We fetch it server-side, so there's nothing to save to your device first.
Does the generated prompt keep my image's aspect ratio?
Yes. Every prompt is generated with your source image's exact aspect ratio appended, including a Midjourney --ar tag, so pasting it into another generator reproduces an image shaped like the one you started with.
What happens to the images I upload?
If you're not signed in, your image is only held in memory to generate the prompt and is never saved anywhere. If you're signed in, it's stored in your private History so you can revisit the prompt later — and you can delete it any time.
Which AI art tools does the output work with?
The prompt is plain structured text, so it drops straight into Midjourney's /imagine, Stable Diffusion front ends like Automatic1111 or ComfyUI, and DALL·E.
How accurate is the generated prompt?
A vision-language model reads the image and writes a literal description, quoting any visible text verbatim rather than paraphrasing it. It's strongest on photos, illustrations, and art — like any AI model it can occasionally misread a busy scene, so it's worth a quick read-over before you paste it into a generator.
What file types and sizes are supported?
JPG, PNG, or WEBP, up to 5MB per image — for both uploads and image URLs.
How is this different from CLIP Interrogator or img2prompt?
Same underlying idea — reverse-engineering a prompt from an image — but built as a hosted, no-setup web app: no Colab notebook, no local install, and output written as one clean structured prompt instead of a raw tag dump.
