100% client-side — your images never leave your device

Color palette from any image,
without the upload.

Extract the dominant colors of a photo in your browser, eyedrop any pixel, and copy them as HEX, RGB or HSL — or export the whole palette.

How it works

  1. 1

    Drop an image

    Add a PNG, JPG, WEBP, GIF or BMP. It's processed locally — nothing is uploaded.

  2. 2

    Read the palette

    The dominant colors are extracted instantly. Choose how many, and switch between HEX, RGB and HSL.

  3. 3

    Pick & export

    Click any pixel to eyedrop its exact color, copy a single swatch or all of them as CSS variables, or download a PNG / .gpl palette.

Frequently asked questions

Is my image uploaded anywhere?+

No. The image is decoded into a canvas and analyzed entirely in your browser. It never leaves your device.

How are the palette colors chosen?+

We use median-cut quantization: the image's pixels are repeatedly split along their widest color axis into evenly populated groups, then each group is averaged. The result is a small set of colors that best represent the whole image, sorted by how much of the image they cover.

Can I get the exact color of one spot?+

Yes. Click anywhere on the preview to use the eyedropper — it reads the exact pixel under your cursor and shows it as HEX, RGB and HSL.

What formats can I export?+

Copy any swatch or pick to your clipboard, copy the whole palette as CSS custom properties, download a labeled PNG strip, or a .gpl file you can load into GIMP, Inkscape and other editors.

Is it free?+

Yes — free, no signup, no watermarks.
