Color Converter
Convert colors between HEX, RGB, and HSL formats
What is the Color Converter?
Written and maintained by the BitConvert team · Feb 27, 2026
The Color Converter translates a single color between the three notations used most on the web: HEX (the #RRGGBB hexadecimal form used in CSS), RGB (red, green, and blue channels from 0 to 255), and HSL (hue in degrees with saturation and lightness percentages). Enter a value in one model and it instantly recalculates the equivalents in the others.
A visual picker and live preview let you eyeball a shade and read off its exact codes, while every value stays in sync as you adjust any one of them. Because HEX, RGB, and HSL all describe the same additive screen color space, the conversions between them are exact — no rounding surprises when you move a brand color from a design tool into a stylesheet.
Key Features
HEX, RGB & HSL
Convert between the three notations CSS and design tools rely on, with values kept in sync as you edit any field.
Live Preview
A swatch updates as you type or pick, showing exactly what the current value looks like on screen.
Visual Picker
Drag through the color picker to explore shades and instantly read back their codes in every format.
Copy Any Format
Copy the HEX, RGB, or HSL string with one click to paste straight into a stylesheet or design file.
Common Use Cases
Turn a brand HEX code into an rgb() value so you can add transparency with rgba() in CSS. Adjust a color using HSL to build lighter or darker variants for hover states and shades in a design system. Match a color picked from a mockup by reading its exact RGB and HEX values for a clean developer handoff. Quickly translate a designer's HSL choice into the HEX code your codebase expects.
