About Image Prompt Generator.

Image Prompt Generator

Build an editable visual prompt from image colors, brightness, aspect ratio and your subject notes. Processing runs on your device. Your source image is not replaced.

Preview and export

The preview uses a smaller copy for responsive adjustments. Download renders the effect again at the original dimensions, including the selected size changes. PNG and WebP support transparent areas; JPG uses your selected background color. Animated inputs are treated as a still image.

What the tool does

This is a local visual-summary generator, not an AI subject recognizer. It measures palette, brightness, contrast and image proportions. Add your own subject notes to make the prompt specific; no image is sent to a vision service.

Local limits

Images up to 50 MB and 40 megapixels are supported. Expanded output is limited to 40 megapixels and 16,384 pixels per side to stay within browser canvas limits.

A LITTLE CLARITY

Good questions. Simple answers.
