How the HEX to RGB Converter works
Enter a HEX color code (with or without #, 3-digit or 6-digit) — RGB and HSL values appear automatically.
Or enter R, G, and B values (0–255 each) to get the equivalent HEX and HSL.
Values convert live as you type; the Convert button also works if you prefer.
Invalid HEX input shows an error message instead of a wrong result.
Tips & tricks
- HSL is easier to reason about when tweaking a color — raise L to lighten, lower S to desaturate, without recalculating RGB by hand.
- 3-digit hex shorthand only works when each channel's two digits match (like #FF5533 → #F53) — anything else needs the full 6 digits.
- There's no copy button — select and copy the HEX/RGB/HSL text directly from the result.
- This tool doesn't support CMYK or 8-digit hex with alpha — for those, use a dedicated design-color tool.

Frequently Asked Questions
How do I convert HEX to RGB?
Split the 6-digit hex into pairs and convert each from hexadecimal to decimal. #FF5733: FF=255 (R), 57=87 (G), 33=51 (B) → RGB(255, 87, 51). The tool does this instantly.
What is the difference between 3-digit and 6-digit HEX codes?
3-digit hex (#RGB) is a shorthand where each digit is doubled: #F53 = #FF5533. Only possible when each pair has identical digits. Both formats represent the same 16.7 million colors.
What is HSL and why is it useful?
HSL (Hue 0-360°, Saturation 0-100%, Lightness 0-100%) is more intuitive for design. To make a color lighter, increase L. To desaturate, decrease S. Much easier to reason about than tweaking individual RGB values.
What is the RGB value of white and black?
White = RGB(255, 255, 255) = #FFFFFF. Black = RGB(0, 0, 0) = #000000. All RGB values equal means a shade of gray.
Does this tool support alpha/transparency (8-digit HEX)?
No — this tool converts standard 3-digit and 6-digit HEX codes only. An 8-digit HEX with an alpha channel (#RRGGBBAA) will show as invalid; strip the last two characters before converting.
What formats does the HEX to RGB support?
The HEX to RGB converts between hex, rgb, rgba, hsl, and more. All conversions work in both directions — instantly, with no sign-up required.
