Complete RGB to HEX Guide

RGB to HEX conversion transforms decimal Red, Green, and Blue channel values (0-255) into a hexadecimal color code. This is the reverse of HEX to RGB conversion, and both formats represent the exact same colors in the sRGB color space.

The conversion takes each decimal value and converts it to a two-character hexadecimal representation. For example, 59 becomes 3B, 130 becomes 82, and 246 becomes F6, giving #3B82F6. The resulting 6-digit hex code is universally supported in CSS, HTML, and all major design tools.

This conversion is useful when you have RGB values from a color picker, programming API, or design specification and need the compact HEX notation for web development or sharing with team members who work with HEX codes.

Converting a decimal number (0-255) to hexadecimal involves dividing by 16. The quotient becomes the first hex digit, and the remainder becomes the second. The hex digits are: 0-9 for values 0-9, and A-F for values 10-15.

Example: Converting RGB 130 to hex. 130 / 16 = 8 remainder 2, so 130 = 82 in hex. Another: 246 / 16 = 15 remainder 6, and 15 = F, so 246 = F6 in hex. In JavaScript, this can be done with value.toString(16).padStart(2, '0').

The padStart ensures single-digit hex values (like decimal 5 = hex 5) are zero-padded to two digits (05), maintaining the consistent 6-character format required for CSS color codes.

CSS Styling

Convert programmatically generated RGB colors to HEX for compact CSS declarations in stylesheets and design tokens.

Design Handoff

Translate RGB values from design tools into HEX codes that developers can paste directly into code.

Color Documentation

HEX codes are shorter and more readable in documentation, style guides, and brand identity files.

Image Processing

After extracting RGB pixel values from images, convert to HEX for use in web interfaces and design tools.

How do I convert RGB to HEX?

Enter the Red, Green, and Blue values (0-255) using the number inputs or sliders. The tool instantly converts them to a HEX color code.

What is the RGB color model?

RGB is an additive color model where Red, Green, and Blue light are combined in various intensities (0-255 each) to produce a broad spectrum of colors. It's the standard for digital displays.

What range do RGB values have?

Each RGB channel ranges from 0 (no intensity) to 255 (full intensity). This gives 256 levels per channel, totaling 16,777,216 possible colors.

How is the HEX code calculated?

Each RGB value (0-255) is converted to a two-digit hexadecimal number (00-FF). The three hex pairs are concatenated with a # prefix to form the 6-digit HEX code.

Is rgb(0, 0, 0) always black?

Yes, rgb(0, 0, 0) is always black because all three color channels have zero intensity. Similarly, rgb(255, 255, 255) is always white.

Can I use sliders to adjust values?

Yes, each channel has both a number input and a range slider. Drag the slider for quick adjustments or type exact values for precision.

Is this tool free?

Yes, completely free with no signup required. Convert unlimited RGB values to HEX.

Why do designers use HEX over RGB?

HEX codes are more compact (#3B82F6 vs rgb(59, 130, 246)) and are the traditional format used in CSS, HTML attributes, and design tools like Figma and Sketch.

Is my data secure?

Yes, all conversions happen locally in your browser. No data is sent to any server.

Can I convert back from HEX to RGB?

Yes, use our HEX to RGB converter tool to perform the reverse conversion.
