Bitwise Calculator — Free Online Tool
Performs bitwise operations (AND, OR, XOR, NOT, left/right shift) on arbitrary-precision integers using BigInt, with a live binary, octal, decimal, and hex breakdown of both operands and the result, plus signed and unsigned interpretations, useful for learning binary arithmetic, designing bit flags and bitmasks, and verifying low-level protocol and hardware register calculations.
