This tool translates a six-digit hexadecimal sRGB color into three decimal RGB channels that can be used in CSS and design documentation.
Designed for: Designers and frontend developers checking CSS color values.
How to use this tool
Enter an optional leading # followed by exactly six hexadecimal digits. Convert returns the red, green, and blue channel values from 0 to 255 and shows a preview swatch.
How the result is produced
Each pair of hexadecimal digits represents one channel. The first pair is red, the second green, and the third blue. The conversion does not change color space or apply a display calibration profile.
Test examples
#000000 becomes rgb(0, 0, 0), #ffffff becomes rgb(255, 255, 255), and #336699 becomes rgb(51, 102, 153).
Limitations
The tool handles six-digit hexadecimal sRGB values only. It does not convert alpha channels, named colors, HSL, OKLCH, wide-gamut color spaces, or calibrated print colors.
Privacy and processing
The color value is parsed locally in the browser and is not uploaded.
