About the Bitwise Calculator
Apply AND, OR, XOR, NOT, NAND, NOR, and bit shifts with the full binary working shown.
What it is
Bitwise operations show up constantly in low-level programming โ flags, masks, permission bits, and packed data. This tool applies any of the standard bitwise operations to your numbers and shows the result as aligned bit columns, so you can see exactly which bits changed and why, at whatever bit width your problem calls for.
Features
Seven operations
AND, OR, XOR, NOT, NAND, NOR, and left/right bit shifts (logical and arithmetic).
Multi-base input
Enter values in decimal, hex (0x), or binary (0b) โ parsed automatically.
Aligned bit-column visualization
Operands and result are shown side by side, bit by bit, grouped in nibbles.
Configurable bit width
Switch between 8, 16, and 32-bit widths to see sign extension and wraparound behavior.
Two's complement handling
Negative numbers are represented correctly at the chosen bit width.
Shift validation
Shift amounts at or beyond the bit width are flagged instead of silently computed.
