HSB to CMYK Converter

How HSB to CMYK conversion works

HSB (also called HSV) represents colors with three components: Hue (0°–360° on the color wheel), Saturation (0–100% from grey to vivid), and Brightness/Value (0–100% from black to full color). It is the model used by most design tools (Photoshop, Figma, Sketch). CMYK represents the same color as ink percentages — Cyan, Magenta, Yellow, and Key (black) — the subtractive model used for print. This tool first converts HSB to RGB, then derives CMYK by pulling out the black (K) channel and scaling the remaining channels accordingly, a standard device-independent approximation. Exact print output depends on your paper, ink, and ICC profile, so treat these values as a starting point. All conversion happens locally in your browser — nothing is uploaded.
