How it works

A hex color is #RRGGBB, where each pair is a 0–255 value written in base 16.
Red = first pair, Green = second pair, Blue = third pair, each converted from hex to decimal.
3-digit shorthand (#abc) expands to 6 digits (#aabbcc) before converting.

Input: #1d4ed8

Output: rgb(29, 78, 216)

1d → 29, 4e → 78, d8 → 216 in decimal.

Input: #fff

Output: rgb(255, 255, 255)

3-digit #fff expands to #ffffff = rgb(255, 255, 255).

Input: #ff8800

Output: rgb(255, 136, 0)

ff → 255, 88 → 136, 00 → 0.

What does #1d4ed8 mean?

Red 0x1d (29), Green 0x4e (78), Blue 0xd8 (216), i.e. rgb(29, 78, 216).

Does it accept colors without #?

Yes, the # is optional. Both 1d4ed8 and #1d4ed8 work.

What about alpha (transparency)?

This tool handles RGB. 8-digit hex with alpha is not converted here.
