Binary, Hex & Alpha Generator

Random bit strings, hex codes and character lists — click the result to copy.

Switch between three formats in one tool: random binary numbers (any bit length from 5 to 1024), hexadecimal codes with optional color swatches, or alpha strings built from a custom character pool.

Generate one value or many at once. Bit-length and hex presets speed up common tasks. For full CSS color names and RGB conversion, visit the Web Colors page.
