Turn a hex color code into its red, green and blue channel values in one step. A hex string like #12b673 packs three pairs of hexadecimal digits, one each for red, green and blue, and this converter decodes them into the 0 to 255 numbers that CSS rgb() and most design tools expect. It accepts both the full six-digit form and the three-digit shorthand, with or without the leading hash, so you can paste whatever you have. The result appears as a ready-to-copy rgb() string plus the raw channel numbers, and a live swatch confirms you decoded the color you meant. It all runs locally in your browser.
