Color Converter Online (HEX, RGB, HSL) — Free
Runs 100% in your browser — your files never leave your device.
Color formats are a handoff problem: design tools speak HEX, CSS often reads better in HSL, and canvas libraries want RGB. Paste any HEX, RGB, or HSL value and get the same color normalized into all three formats, ready to copy. The conversion runs entirely in your browser.
How it works
- 1
Paste a color
Enter any HEX, RGB, or HSL value — or pick one with the visual color picker.
- 2
Read the formats
The same color appears normalized as HEX, RGB, and HSL at once.
- 3
Copy what you need
One click copies any format to your clipboard.
About this tool
How the conversion works
The tool parses whatever color notation you paste, converts it internally to a standard model, and renders the same color as HEX, RGB, and HSL simultaneously. The math is exact round-tripping — no rounding drift between formats, so every output describes the identical color.
When to reach for it
Design handoffs are the classic case: the mockup speaks HEX, the CSS variable wants HSL for easy alpha tweaks, and a canvas library wants RGB tuples. Converters also settle arguments — paste two suspiciously different values and see whether they are actually the same color.
For one-direction conversions
If you only ever need one direction, the dedicated HEX to RGB and RGB to HEX pages open with that exact job set up. The converter is the version that shows everything at once.
Frequently asked questions
What notations can I paste?
HEX with or without the hash (3- and 6-digit), RGB and RGBA functions, and HSL and HSLA functions. The tool accepts them all and normalizes the result.
Why do the numbers differ between formats for the same color?
The formats describe the same color in different coordinate systems — HEX is a compact RGB form, while HSL describes hue, saturation, and lightness. Different numbers, identical color on screen.
Does the converter support transparency?
RGBA and HSLA inputs keep their alpha through the conversion and show it in the output. HEX output stays 6-digit, so use RGB or HSL when you need the alpha channel carried along.
