Binary & Hex Playground

Convert integers and explore their bits. Everything runs in your browser; values are not saved.

Decimal follows the selected signed range. Binary and hex are raw bit patterns: in signed mode, a leading 1 bit means a negative number. Changing the base reinterprets your input. Overflow is rejected, never silently wrapped.

Bit positions run from most significant to least significant (bit 0). Toggle a bit with a click, Enter or Space. NOT flips only the selected number of bits and ignores operand B. Signed mode changes the decimal interpretation, not the bitwise operation.
