About Color Palette Extractor

Overview

The Color Palette Extractor turns any uploaded image into a practical design palette directly in your browser. It analyzes the image locally, groups similar pixels into dominant colors, and gives you production-ready values for branding, UI design, CSS, Tailwind, documentation, and accessibility review. No image is uploaded to a server, so screenshots, mockups, and private brand assets stay on your device.

FAQ

Are my images uploaded anywhere?

No. The image is decoded and analyzed in your browser using canvas APIs. The file never leaves your device.

Why do extracted colors differ slightly from manual picking?

Dominant colors are cluster averages across many similar pixels, while the eyedropper samples one exact pixel. Use dominant colors for palettes and the eyedropper for exact brand or UI values.

Which export should developers use?

CSS variables are best for plain CSS, SCSS variables are convenient for Sass projects, Tailwind config works for Tailwind design tokens, and JSON is ideal for build tools or design-token pipelines.
