Technical notes
Color Converter converts each pair of hex digits to a 0–255 value for red, green and blue (and back), then derives HSL from those channels.

Nothing you type is uploaded — the calculation happens entirely on your device.
FAQ
What does this output?
It takes a hex colour and shows its RGB and HSL values.
Can I use a 3-digit hex like #f80?
Yes. Short hex codes are expanded automatically, so #f80 becomes #ff8800.
Does it need the # sign?
No. You can enter the hex with or without the leading #.
Does the Color Converter send my data to a server?
No. The Color Converter runs entirely in your browser, so nothing you enter is uploaded, stored, or shared.
Worked example
The colour #FF8800 converts to RGB(255, 136, 0) — hex pairs FF, 88, 00 equal 255, 136, 0 in decimal.
