Color Converter
Color Converter converts a three- or six-digit hexadecimal colour into its red, green and blue channel values and rounded HSL coordinates. Enter a HEX code with or without the # sign; the calculation runs in your browser.
Enter your hex colour and Color Converter works out the colour in each format with hex, RGB and HSL channel maths — fast, free and private, with no sign-up or uploads.
About this calculator
Color Converter converts each pair of hex digits to a 0–255 value for red, green and blue, then derives HSL from those channels. It matters when a format, encoding or size has to be exactly right for the system reading it. Here is the calculation on real numbers: The colour #FF8800 converts to RGB(255, 136, 0) — hex pairs FF, 88, 00 equal 255, 136, 0 in decimal. For your own figures, use the calculator above — same method, your inputs, computed on-device.
How to use
- Type a hex colour like #ff8800.
- Press Calculate to convert the colour.
- Read the RGB and HSL values.
- Use them in your design tools.

Technical notes
This form accepts opaque three- or six-digit HEX codes and outputs RGB plus HSL rounded to whole degrees and percentages. It does not accept RGB input, transparency, named colours or a printing profile. Use the RGB to HEX Converter for the reverse direction.
Results are reference values; validate against your own environment before relying on them in production.

FAQ

Does it need the # sign?
No. You can enter the hex with or without the leading #.
