HEX ↔ RGB Converter (Color Code & CSS Format Converter)
Convert color codes between HEX, RGB, RGBA, HSL, HSLA, and CMYK with live swatch preview.
TL;DR: HEX ↔ RGB Converter provides instant two-way conversion between HEX, RGB, HSL, and CMYK color representations.
How Do I Convert HEX Color Codes to RGB and HSL?
To convert a 6-digit HEX color code (e.g. `#7B2FF7`) to RGB, convert each 2-digit hex pair from base-16 to decimal: `7B` = 123 Red, `2F` = 47 Green, and `F7` = 247 Blue (`rgb(123, 47, 247)`). HSL is calculated by finding the maximum and minimum RGB values to derive Hue angle (0–360°), Saturation %, and Lightness % (`hsl(263, 93%, 58%)`).
How to Use the HEX ↔ RGB Converter
Our HEX ↔ RGB Converter is engineered for rapid developer workflow, high-performance in-browser execution, and complete code privacy.
- Enter a color value in any format: HEX (`#7B2FF7`), RGB (`rgb(123, 47, 247)`), or HSL (`hsl(263, 93%, 58%)`).
- Or pick a color using the visual color picker swatch.
- Adjust the alpha transparency slider (0% to 100%).
- The tool calculates conversions across all color models simultaneously.
- Click on any color format card to copy the CSS code.

Frequently Asked Questions
- It is a design and developer utility that converts hexadecimal web color codes into RGB, HSL, CMYK, and CSS color declarations.
- Type your HEX code (e.g. `#3b82f6`) into the converter. The tool breaks the hex string into Red, Green, and Blue decimal values (`rgb(59, 130, 246)`).
- A 3-digit hex code (`#fff`) is shorthand for repeating digits (`#ffffff`). 8-digit hex codes (`#ffffff80`) include a 2-digit alpha transparency value.
- HSL represents color by Hue (0–360° position on the color wheel), Saturation (0% gray to 100% full color), and Lightness (0% black to 100% white).
- CMYK (Cyan, Magenta, Yellow, Key/Black) is a subtractive color model used in physical printing presses, whereas RGB is an additive model used for digital screens.
- Yes. Adjust the opacity slider to generate `rgba(123, 47, 247, 0.85)` and `hsla(263, 93%, 58%, 0.85)` CSS properties.
- Yes. All color space math executes 100% locally in your web browser.
- Yes. The converter displays calculated contrast ratios against white and black backgrounds to ensure accessibility compliance.
