Hex to RGB Converter

Hexadecimal color codes dominate web development — every CSS stylesheet, design token, and brand guideline references colors as #RRGGBB strings. RGB (Red, Green, Blue) expresses the identical color as three decimal numbers from 0 to 255, which JavaScript canvas APIs, Python imaging libraries, and spreadsheet conditional formatting expect. Converting between the two formats is a daily task for front-end developers and digital designers.

Enter a Hex code with or without the leading hash. Three-digit shorthand (#F00) expands to six digits (#FF0000) by doubling each character. Six-digit standard Hex splits into three byte pairs: the first pair is red intensity, the second green, the third blue. Each pair converts from base-16 to decimal — #FF equals 255, #00 equals 0, and #80 equals 128.

Eight-digit Hex (#RRGGBBAA) adds an alpha channel for transparency. The fourth pair maps to opacity where FF is fully opaque and 00 is fully transparent. The converter outputs both rgb() and rgba() CSS function syntax ready to paste into stylesheets.

Invalid characters or wrong-length codes trigger clear error messages rather than silent wrong output. Copy the RGB result for use in React inline styles, Android XML colors, or Unity material properties. Reverse the process with the RGB to Hex converter when a design tool exports decimal channels.

Whether you are translating a Figma Hex export for a Canvas animation, debugging a mismatched color between CSS and JavaScript, or learning how digital colors encode on screen, Hex-to-RGB conversion makes the underlying channel values visible.
