Does it support 3-digit shorthand hex codes?

Yes. A shorthand code like #abc is expanded by doubling each digit to #aabbcc before conversion, so #abc decodes to rgb(170, 187, 204). Both 3- and 6-digit forms are accepted with or without the leading hash.

What range are the RGB values?

Each of the red, green, and blue channels runs from 0 to 255, which corresponds to the hexadecimal range 00 to FF. Entering a value outside 0-255 is rejected as invalid.

Why does my hex code show in uppercase?

Hex letters A-F are case-insensitive, so #ff8800 and #FF8800 are the same color. The converter normalizes output to uppercase for consistency, but you can type either case as input.

Does this handle alpha or opacity (8-digit hex)?

No. This tool converts solid RGB colors only, using 3- or 6-digit hex. Eight-digit codes that include an alpha channel are not supported, so drop the final two digits before converting.

This color converter translates between hex codes and RGB triplets in both directions. A hex code packs three color channels into six hexadecimal digits, two per channel, where each pair ranges from 00 to FF (0 to 255 in decimal). Paste a code such as #FF8800 to read off its red, green, and blue values, or enter three 0-255 numbers to build the matching hex code for CSS, design tools, or markup.

Formula

R = hex[0:2]16, G = hex[2:4]16, B = hex[4:6]16 (and the inverse)

R: Red channel, 0-255
G: Green channel, 0-255
B: Blue channel, 0-255
16: Value read as a base-16 (hexadecimal) number

How it works

Pick a direction: Hex to RGB to decode a color code, or RGB to Hex to assemble one from channel numbers.
For hex input, the tool strips any leading # and expands 3-digit shorthand (#abc becomes #aabbcc) before reading each two-digit pair as a base-16 number from 0 to 255.
For RGB input, each 0-255 channel is converted to a two-digit hexadecimal value and the three are joined into a #RRGGBB string. A live swatch previews the resulting color.

Worked example

Decode the hex color #FF8800 into RGB channels.

FF in base 16 = 15x16 + 15 = 255 (red).
88 in base 16 = 8x16 + 8 = 136 (green).
00 in base 16 = 0 (blue).

rgb(255, 136, 0) — R 255, G 136, B 0.
