Image Prompt Builder
Structure an image-generation prompt from subject, style, composition, lighting, color, mood, aspect ratio, and negative guidance. The tool only combines your text and never calls an AI service.
Build a structured image-generation prompt locally by combining a required subject with optional style, composition, lighting, color, mood, aspect ratio, and avoid instructions.
How to build an image prompt
- Describe the main subject first.
- Add any style, composition, lighting, color, mood, aspect ratio, or negative guidance you need.
- Generate the combined text and copy it into the image tool of your choice.
How the builder works
The tool simply joins the filled text fields in a predictable order, adds an aspect-ratio sentence when selected, and adds an Avoid sentence when negative guidance is present.
It does not call an AI model, judge prompt quality, translate text, or guarantee how any particular image model will interpret the result.
Privacy and limitations
All prompt text is assembled in your browser and this tool sends no request to an image-generation service. You decide where to paste the generated prompt afterward.
