Convert HEX/RGB to and from OKLCH and OKLab (CSS Color 4). OKLCH Color Converter is a free online tool from the ToolsRift Color Tools collection. It runs entirely in your browser — nothing to install, no signup, and your data never leaves your device.
Enter a color as HEX, RGB or OKLCH; the tool converts between OKLCH, OKLab and hex and shows a live swatch to copy.
A perceptually uniform color space (Lightness, Chroma, Hue) from CSS Color 4 where equal numeric changes look like equal visual changes.
OKLCH keeps perceived lightness consistent across hues, so palettes and gradients look smoother and more even than in HSL.
Yes — the oklch() function is supported in all current major browsers; a hex fallback is still wise for older ones.
