What the HEX to RGB does

Paste a hex colour code like '#1E90FF' and get its RGB values: rgb(30, 144, 255). The hash sign is optional, and three-digit shorthand like '#0af' works too.

Each pair of hex digits is one colour channel — red, green and blue — from 00 (none) to FF (255, full).

Why the HEX to RGB is useful

Designers hand over colours in hex, but plenty of places need RGB: CSS with transparency, Android and iOS code, video software and some print tools.

Converting by hand means doing base-16 maths three times; here it's instant and exact.

Also known as: hex to rgb, color converter, free hex to rgb, online hex to rgb, hex to rgb online free, hex to rgb tool, best hex to rgb tool.
