About

ImagePromptGuru is a free web-based prompt generator that turns an existing image or a short piece of text into a descriptive prompt suitable for AI image generators. Many people struggle to phrase prompts well enough to get useful results from tools like Midjourney or Stable Diffusion, and this site addresses that gap by analyzing a picture or a rough idea and rewriting it in the structured language those models respond to.

The service runs entirely in the browser at imagepromptguru.net and requires no account. Users upload a JPG, PNG, or WEBP file (up to 5MB) or paste an image URL for the Image to Prompt mode, or type a description for the Text to Prompt mode. In both cases they can pick a target model and one of 18 interface languages before generating. The tool is positioned as free to use without watermarks, subscriptions, or registration.

Key Features

Image to Prompt: Analyzes an uploaded picture or image URL and produces a descriptive prompt that captures its visual content, which is useful for recreating or iterating on a reference photo or sketch.
Text to Prompt: Takes a plain-language idea and rewrites it using AI art prompt conventions, helping users who know what they want but lack the phrasing skills to express it.
Model-specific optimization: Prompts can be tailored for Midjourney, DALL·E, Stable Diffusion, Flux, or a general format, matching the syntax preferences of each generator.
Style presets: Text to Prompt offers scene and style options including Photorealistic, Ghibli, Cyberpunk, Fantasy, Anime, Watercolor, Oil Painting, and Steampunk.
Multilingual input: The interface supports 18 languages such as Spanish, Chinese, Japanese, Arabic, French, and German; prompts are output in English, the common standard for AI art models.
No registration: The tool works without an account, and prompt history is stored locally in the user's browser rather than on a server.
Instant image disposal: Uploaded images are processed in real time and then discarded, with no storage, sharing, or use for model training, according to the site's FAQ.

Pricing & Fees

  • Pricing: Free forever according to the site, with no subscriptions, watermarks, or hidden costs.
  • Commercial use: Generated prompts belong to the user and can be used for personal, client, or commercial projects without restrictions.
  • Upload limits: Image uploads accept JPG, PNG, or WEBP files up to 5MB, and an image URL input is offered as an alternative.
  • Language support: 18 interface languages are available for input, with English prompt output.

Who It's For

ImagePromptGuru suits digital artists and designers who want to reverse-engineer prompts from reference images, hobbyists learning how to phrase prompts for Midjourney or Stable Diffusion, and content creators who need consistent visual styles for marketing or social media. It also fits educators and beginners exploring AI image generation without paying for prompt tools, and non-native English speakers who can describe an idea in their own language and receive a polished English prompt in return.
