HEX to RGB Converter · supports alpha transparency · component channel visualization

How it works

Convert your color in three steps

1. Enter your HEX code

Type or paste a HEX color code into the input field, with or without the # prefix. Shorthand 3-digit codes (e.g., #fff) and 8-digit HEX codes with an alpha channel are fully supported.

2. View all converted values

The tool instantly outputs the equivalent RGB, RGBA, HSL, and HSLA values alongside a color preview swatch for visual confirmation of the result.

3. Copy the format you need

Click the copy button next to any output format to copy that specific value to your clipboard, ready for use in CSS, JavaScript, or any design application.

FAQ

Common questions

A 6-digit HEX code encodes three pairs of hexadecimal digits — one pair each for the red, green, and blue channels. Each pair represents a value from 00 (decimal 0) to FF (decimal 255). To convert, each pair is read as a base-16 number and translated to its decimal equivalent. For example, #3a86ff breaks down as: red = 3A (58 decimal), green = 86 (134 decimal), blue = FF (255 decimal), producing rgb(58, 134, 255). Three-digit shorthand codes like #fff are expanded by doubling each character: #ffffff.
An 8-digit HEX code (sometimes called HEX8) adds a fourth two-character pair after the standard RGB channels to encode opacity. For example, #3a86ff80 means the base color #3a86ff at approximately 50% opacity (80 in hex = 128 in decimal, which is roughly 50% of 255). This format is supported in modern browsers in CSS and is a compact alternative to RGBA. It is less commonly encountered than RGBA in codebases, but is widely output by modern design tools when exporting transparent color values.
Both RGB and HEX describe the same colour space, so the choice is primarily one of workflow preference and context. HEX is compact and universally recognised in HTML and CSS. RGB is preferred when manipulating color values programmatically in JavaScript, or when adding a transparency channel using RGBA. HSL is increasingly popular in CSS design systems because it allows intuitive adjustments to lightness or saturation without affecting the hue. This tool outputs all three formats simultaneously so you can choose whichever suits your immediate use case.
This converter processes one color at a time and is designed for quick individual lookups. For batch conversion of many color values — such as converting an entire design token file — a script or build-tool integration would be more efficient. CSS preprocessors like Sass and Less include built-in color functions that can handle conversions at build time. For occasional one-off conversions during design and development work, this tool handles each one instantly without any configuration or setup.
