Palette Extractor is a free image tool that runs entirely in your browser — pull dominant colors from an image. No upload, no account, no limits.
Extract the dominant colors from any image. Drop a photo, logo or screenshot and the tool samples its pixels and runs a median-cut quantizer to build a palette of 4 to 16 representative colors — each with its HEX value and share of the image. Click any swatch to copy it, or copy the whole palette as a hex list or CSS custom properties. Everything runs on the Canvas API in your browser; the image is never uploaded.
The image is downscaled, its pixels are sampled, and a median-cut algorithm splits them into color boxes — the average of each box becomes a palette color, sorted by how much of the image it covers.
Yes — the whole palette copies as CSS custom properties, or as a plain hex list if you would rather paste it somewhere else. Clicking a single swatch copies just that colour.
Every calculation happens on this page, in your own browser. Your input is never sent to a server, never logged and never used for training — which also means the tool keeps working when you are offline.
