Image Palette Extractor

No. The image never leaves your browser. It's decoded, downsampled, and analyzed entirely on your device using the Canvas API and a Web Worker — nothing is sent over the network. That's both a privacy guarantee and why it works offline once the page has loaded.

The tool uses modified median-cut quantization — the same approach color-thief uses — which recursively splits the image's colors into buckets and picks a representative for each. It runs in a Web Worker so the page stays responsive even for large images. Large uploads are downsampled first to keep it fast.

Choose 4 to 12. Fewer colors give you the broad, dominant tones; more colors surface secondary accents. The image is only read once — changing the count re-runs the quantization on the cached pixels, so it's instant.

Click any swatch to copy its hex, or copy the whole palette as CSS custom properties (`--palette-1`, `--palette-2`, …) or a JSON array. Pair it with the converter to fine-tune a color, or the theme builder to turn one into a full Tailwind scale.

Median-cut favors colors by area, and near-white and fully transparent pixels are skipped so backgrounds don't dominate. A color that catches your eye but covers little area may not appear; raising the color count usually surfaces it.
