Overview

Image to Prompt is a web tool that turns an uploaded image into a text prompt. The homepage positions it as a way to describe images in words and generate prompts that can be reused in other AI image tools.

The workflow is simple: upload an image or use an image URL, choose a prompt mode and model target, and generate a result in seconds. The site presents the service as free, with no login required and unlimited generations stated on the homepage.

Features

Image input options

Upload a file or provide an image URL, then generate a text prompt from the source image.

Model-specific prompting

Choose from General Prompt, Nano Banana, Flux, Midjourney, or Stable Diffusion to shape the output for different generation targets.

Speed and quality modes

Switch between Fast and Advance modes to trade speed against more detailed output.

English output option

Select English as the output language; the page notes that the major models currently offer the most friendly support for English prompts.

Prompt generation workflow

Copy the generated prompt from the output box after generation completes, and review prompt history on the page.

Use Cases

Prompting from reference images
Turn a reference image into a prompt that can be reused in another AI image model, especially when you want a text description before generating variations.
Targeting a specific image model
Create model-specific prompts for platforms such as Midjourney, Flux, or Stable Diffusion using the page’s dedicated prompt modes.
Using image URLs as input
Work from a shared image link instead of uploading a local file when the source image is already hosted online.
Describing visuals for team review
Generate a quick text description for a design sketch or visual concept when you need a readable prompt for discussion or iteration.
Quick, no-login prompt creation
Generate prompts without signing in when you want a low-friction, browser-based workflow for one-off conversions.
