Is my image uploaded to a server?

No. Loading, downscaling, and color extraction all run in your browser with JavaScript, and the image is never uploaded anywhere.

How are the colors chosen?

It uses median cut, a classic color-quantization algorithm. All pixels start in one box; the box is repeatedly split at the median of its widest channel (R / G / B) until there are as many boxes as the requested color count, and each box's average color becomes a representative. The share is the fraction of pixels in that box.

Why don't the shares add up to exactly 100%?

Each share is rounded to one decimal place for display, so rounding can make the total 99.9% or 100.1%. Internally all pixels are treated as 100%. Transparent pixels (low alpha) are excluded from the count.

Why do I sometimes get fewer colors than requested?

Boxes whose representative color rounds to the same HEX are merged into one and their shares summed. For near-solid images this can produce fewer colors than the count you selected.

Do photos and illustrations give different results?

Photos have many in-between tones from gradients and shading, so several similar neighboring colors may be extracted. Flat illustrations and logos tend to surface their original distinct colors directly. Adjust the color count to suit your needs.

Image Color Palette Extractor

Drop an image to extract its dominant colors via median-cut quantization, with each color's HEX / RGB value and share. Choose how many colors (4–16) and see the balance in a proportional bar. Click a color to copy its HEX, or copy the whole palette as a HEX list, CSS variables, or JSON. Images are analyzed entirely in your browser and never uploaded.

How to use

Drag an image onto the drop area or load it with "Choose file" and the dominant colors are extracted automatically via median-cut quantization. Change "Colors" to pick how many colors (4–16) to extract; results are ordered by share, highest first. Click any color's HEX to copy that color, or use "Copy palette" to copy the whole palette as a HEX list, CSS variables, or JSON. The proportional bar shows the balance of the palette at a glance. All analysis runs entirely in your browser and nothing is uploaded.
