How to Generate AI Art Prompts from an Image or Text (Free, No Login)

Updated

Use the Image to Prompt mode when you already have a photo or sketch, and the Text to Prompt mode when you only have a rough idea. Both modes run in the browser with no account, and the generated prompt comes out in English so it can be pasted into Midjourney, DALL·E, Stable Diffusion, or Flux. The steps below cover inputs, settings, and what to check when the output misses.

Before you start

  • Image to Prompt: a JPG, PNG, or WEBP file no larger than 5MB, or a direct image URL.
  • Text to Prompt: a short description of the scene, subject, or mood you want.
  • Target model: know which generator you will paste into, because the optimizer changes the prompt style per model.
  • Language: you can type in any of the 18 supported languages; the prompt itself is returned in English.

Generate a prompt from an image

  1. Open the site and stay on the Image to Prompt tab.
  2. Upload a file or paste an image URL. The upload area accepts JPG, PNG, and WEBP up to 5MB.
  3. Pick an AI model under the optimizer: General, Midjourney, DALL·E, Stable Diffusion, or Flux.
  4. Choose an output language if you want the interface or supporting text in your own language.
  5. Click Generate Prompt and copy the result.

Expected result: a descriptive prompt that captures the subject, composition, lighting, and style of the image, formatted for the model you selected.

When to use the URL option

Paste an image URL when the picture is already online and you do not want to download it first. The same 5MB limit applies to the fetched file, so very large hosted images may fail.

Generate a prompt from text

  1. Switch to the Text to Prompt tab.
  2. Enter your description in the text field.
  3. Select a Scene/Style: General, Photorealistic, Ghibli, Cyberpunk, Fantasy, Anime, Watercolor, Oil Painting, or Steampunk.
  4. Click Enhance Prompt to expand your idea into a fuller prompt.

Expected result: your rough sentence becomes a detailed prompt with art-direction phrasing, while keeping the subject and style you chose.

Choosing between the two modes

Your situation Use this mode Why
You have a photo, screenshot, or sketch to reproduce Image to Prompt It reads visual content and describes it
You have a written idea but weak phrasing Text to Prompt It expands and professionalizes your description
You want a specific art style applied Text to Prompt with a Scene/Style Style presets steer the output
You need model-specific syntax Either mode, with the model optimizer set The optimizer adapts the prompt per generator

Get better results

  • Match the model to your generator. A Midjourney-optimized prompt will not carry the same phrasing as a Stable Diffusion one; regenerate if you switch tools.
  • Use style presets deliberately. Ghibli and Cyberpunk push strong aesthetics; leave the style on General if you want the prompt to stay close to your input.
  • Iterate on the prompt, not the image. If the first output is too vague, add detail to your text or try a different style before re-uploading.
  • Write in your native language. Input in Spanish, Japanese, Chinese, Arabic, French, German, and other supported languages is accepted; the prompt returns in English, which is the common standard for AI art tools.

Verify the output

Before pasting into your generator, check that the prompt names the subject, the setting, the lighting or mood, and the style. If a key element is missing, regenerate or add it to your text input. Then paste the prompt into Midjourney, DALL·E, Stable Diffusion, or Flux and compare the result against your original image or idea.

Common snags

  • Upload rejected: the file is likely over 5MB or not JPG, PNG, or WEBP. Resize or convert it first.
  • Prompt feels generic: switch the model optimizer or add a Scene/Style, then regenerate.
  • Non-English input returns English output: this is expected; the prompt is always produced in English for compatibility with AI art tools.
  • Privacy concern: uploaded images are processed in real time and discarded, and prompt history is stored locally in your browser rather than on an account.
