Turn Any Image into an AI Prompt (and Get Closer to the Look You Want)
You find an image with a style you love, then spend an hour trying to describe it to an AI image tool. The words never quite match. The Image to Prompt tool works backwards: you give it an image, and it writes the text prompt that could produce a similar one. Here is how to use it well, and where its limits are.
What a good image prompt contains
- Subject and setting: what is in the picture and where it is.
- Style or medium: a photograph, a flat illustration, a 3D render, a watercolour.
- Lighting: golden hour, soft studio light, harsh midday sun, neon at night.
- Camera look: close-up or wide, shallow depth of field, a lens feel such as 35mm.
- Colour palette: the two or three colours that define the mood.
- Composition and ratio: where the subject sits in the frame, and the shape of the image.
Image to Prompt looks for each of these, then adds a negative prompt (things you want the AI to avoid) and a suggested aspect ratio.
Why page owners use it
- Keep a consistent look. Turn one of your best-performing images into a prompt, then reuse the style with new subjects.
- Learn what makes an image work. Seeing the lighting and composition written out helps you spot the pattern.
- Save time. Start from a strong prompt and change two or three words, instead of writing from nothing.
The walkthrough
1
Add your image
Upload a JPG, PNG or WebP file up to 10 MB, or paste a direct https link to an image file. Links to social media pages cannot be read, so save the image and upload it instead.
2
Choose your AI tool and detail level
Pick General, Midjourney, ChatGPT / DALL·E, Gemini or Stable Diffusion / Flux. The wording changes to suit that tool. Choose Short for a quick prompt or Detailed for more control.
3
Analyze and read the result
You get the prompt, a negative prompt, and a breakdown of style, lighting, camera, colours, composition and ratio. You can edit the prompt right in the box.
4
Copy it into your AI tool
Use the copy buttons for the prompt, the negative prompt, or everything at once. Press “Try another version” if you want different wording.
How to get better results
- Swap the subject, keep the style. Replace the subject in the prompt with your own and leave the lighting, colours and camera words alone.
- Be specific about the one thing that matters. If the lighting is what you love, add more detail about the lighting.
- Use the negative prompt. Tools that support it use it to avoid blur, text and watermarks.
- Match the ratio. Generate in the suggested shape, such as 4:5 for a taller feed post, so you do not have to crop.
- Generate a few times. AI tools produce a new image each run, so pick the best of several.
An honest word about limits
An AI prompt is not a copy machine. The same prompt gives different pictures in different tools, and even in the same tool from one run to the next. Expect a result that is close in look and mood, not a match. The tool also describes only what it can see, so small details may be missed. Read the prompt and fix anything that is wrong before you use it.
Use images you have the right to use. A prompt describes a look. Do not use this tool to copy another creator's work, to imitate a real person's likeness, or to create misleading images. The tool describes people in general terms and does not identify them. Your image is shrunk in your browser and sent to Google's Gemini AI only to write the prompt, and PostPix does not save it. Some platforms and countries also have rules about labelling AI-generated images, so check the rules for where you post.
Next steps
Once you have your image, resize it for each platform with Export for Other Platforms, write the words with the Caption & Bio Writer, and check it with the Policy Checker before you post.
