Binary to Hex Converter: Fast and Simple

What This Converts

The converter reads a binary string, parses it as a base-2 integer, then re-expresses that integer in base 16. Enter 10101010 and it converts to decimal 170 first, then to hex: the result is 0xAA. Try 11111111 and you get 0xFF (255 in decimal) — the maximum value a single byte can hold.

Input Rules

Only the characters 0 and 1 are accepted; anything else (spaces, a "0b" prefix, stray letters) triggers the validation message instead of a result. Output is always uppercase hex with a "0x" prefix, and no leading zeros are added — a 4-bit value like 1010 becomes 0xA, not 0x0A.

Where This Comes Up

Binary-to-hex conversion is routine when reading memory dumps, packet captures, or color values expressed in binary. Hex is preferred over raw binary in these contexts because each hex digit maps cleanly to exactly 4 bits, so a full byte fits in two hex characters instead of eight binary ones.
