FAQ

RGB defines a color using Red, Green, and Blue channels (0–255 each). RGBA adds an Alpha channel (0–1) that controls transparency: 0 is fully transparent, 1 is fully opaque.

When alpha is less than 1, it is appended as a two-digit hex byte at the end of the 6-digit color code, giving an 8-digit hex like #RRGGBBAA.

Yes. This tool accepts #RGB (e.g. #F0A), #RGBA, #RRGGBB, and #RRGGBBAA formats in the Hex → RGBA mode.
