# Colour Converter Convert a colour between HEX, RGB, HSL, HSV and CMYK — type any CSS colour or pick one. Everything is computed in your browser. ### How it works Your input is parsed by the browser’s own colour engine (via a canvas `fillStyle` round-trip), so any valid CSS colour works — a hex code, an `rgb()`/`hsl()` function, or a named colour like `rebeccapurple`. The resulting RGB is then converted with the standard formulae to HSL, HSV and CMYK. Click any value to copy it. All local, nothing uploaded. --- *Source: [ocxly.com/color-converter.html](https://ocxly.com/color-converter.html) — OCXLY, free 100% client-side privacy-first tools. Free colour converter.
