About This Calculator
Each RGB channel (0–255) is converted to a two-digit hexadecimal number, then joined as #RRGGBB.
If alpha is below 100%, the tool outputs an 8-digit hex (RRGGBBAA) plus the equivalent rgba() CSS — handy where older browsers need the function form. Hex values are uppercase for consistency.
Conversion runs instantly in your browser.
