Hex to RGB Converter

Convert hex color codes to RGB values instantly — with color preview and CSS output

What Is Hex to RGB Conversion?

Hex to RGB conversion translates hexadecimal color codes into their Red, Green, Blue component values. A hex color like #3B82F6 is a 6-character string where each pair of characters represents one color channel in base-16: 3B (59 in decimal) for red, 82 (130) for green, and F6 (246) for blue. The RGB equivalent is rgb(59, 130, 246). Both representations describe the exact same color.

This conversion is frequently needed when working across different CSS formats, translating design specifications (Figma and Sketch often use hex) to CSS rgb() or rgba() functions, performing color calculations that require numeric values, and integrating colors into JavaScript canvas operations or SVG attributes that use RGB format. Understanding both representations helps developers and designers communicate color values precisely across tools and codebases.

How to Convert Hex Colors to RGB

1. Enter a hex color code (with or without the # prefix) into the input field
2. The RGB values appear instantly along with a live color preview swatch
3. Copy individual R, G, B values or the complete CSS rgb() function
4. Use the color picker to visually select a color and get both hex and RGB output
5. Support for 3-character shorthand hex (#F00) and 8-character hex with alpha (#3B82F680)

Why Use PinusX for Hex to RGB Conversion?

PinusX performs color conversion with 100% client-side processing. While color values are not typically sensitive data, the tool embodies PinusX's core principle that developer tools should process everything locally. Every conversion, preview, and CSS output generation happens in your browser without server communication. In November 2025, jsonformatter.org leaked over 80,000 user credentials because of server-side processing — a reminder that even seemingly simple tools can compromise privacy when they transmit user data. PinusX keeps everything in your browser tab by design.

Frequently Asked Questions

How do hex color codes work?

Hex colors use base-16 (hexadecimal) digits 0-9 and A-F. The 6-character code is three pairs: first pair is red (00-FF = 0-255), second is green, third is blue. FF means maximum intensity (255), 00 means none (0). For example, #FF0000 is pure red (255, 0, 0) and #000000 is black (0, 0, 0).

What is the difference between hex and RGB?

They represent the same colors using different number systems. Hex uses base-16 in a single string (#RRGGBB). RGB uses base-10 decimal values for each channel (rgb(R, G, B) where each value is 0-255). Hex is more compact in CSS and widely used in design tools. RGB is easier for programmatic color manipulation.

Can I convert 3-character hex codes?

Yes. 3-character hex like #F00 is shorthand where each character is doubled: #F00 expands to #FF0000 (pure red). Our converter accepts both 3 and 6-character formats and also 8-character hex with alpha channel (#3B82F680 where 80 is the alpha value).

How do I include transparency with RGB?

Use the rgba() CSS function: rgba(59, 130, 246, 0.5) where the fourth value is alpha (0 = fully transparent, 1 = fully opaque). In hex, an 8-character code includes alpha as the last two characters: #3B82F680 where 80 hex = 128 decimal = 50% opacity.

Can I convert RGB back to hex?

Yes. Use our RGB to Hex converter for the reverse operation. Converting back and forth is lossless — both formats represent exactly the same 16.7 million possible colors (256 values per channel, 256^3 = 16,777,216 total colors).
