How do I use the Colour Palette Extractor to get hex codes from an image?

Open the Colour Palette Extractor in img-tools and load your image by dragging and dropping it, clicking to browse, or pasting — JPEG, PNG, WebP, and AVIF are supported. The dominant colours instantly appear as swatches ordered by coverage, each labelled with its HEX code; click any swatch to copy its hex or use Copy all HEX to grab the whole palette. It is completely free and runs in your browser with no upload, so your image never leaves your device.

Are images uploaded to a server?

No. The palette is computed entirely in your browser; your image never leaves your device.

How are the colours chosen?

The tool downscales the image for sampling, then uses median-cut quantisation to group similar pixels into a small set of representative colours, sorted by how common they are.

How do I copy a colour?

Click a swatch to copy its hex code, or click Copy all HEX to copy every colour in the palette.

Median-cut is a classic colour-quantisation algorithm that repeatedly splits the colour space along its widest axis to choose a representative palette.
Sampling a downscaled copy of an image yields a representative palette far faster than scanning every full-resolution pixel.
A hex colour code encodes red, green, and blue each as a 0–255 value in two hexadecimal digits (e.g. #3b82f6).
Computing the palette client-side keeps the image on your device — no upload, and it works offline.
Dominant-colour palettes are widely used for brand colour matching, theme generation, and design inspiration.
