Convert red, green and blue channel numbers into a single hex color code. RGB is how screens actually build color, mixing three channels from 0 to 255, while hex is the compact notation CSS, SVG and design files love because it fits a whole color in six characters. Type each channel, or paste a full rgb() string, and this tool assembles the matching #rrggbb value while showing a live swatch so you can confirm the result at a glance. Values are clamped to the valid 0 to 255 range so a stray digit never produces a broken code. The output copies with one click and everything is computed in your browser with nothing sent anywhere.
