Bitwise Calculator

Apply AND, OR, XOR, NOT, NAND and NOR to two values and inspect the result one bit at a time.

Bitwise operations

Binary: —
Hex: —
Decimal: —
Bits are listed from the most significant bit down to bit 0, so the table matches the binary string.

How to use the Bitwise Calculator

  1. Choose the input format, the operation and the bit width.
  2. Enter the two values you want to combine.
  3. Read the result and check the per-bit table underneath.

Frequently Asked Questions

Common questions about the free online bitwise calculator.

AND keeps a bit only when both values have a one in that position, so it is often used to mask bits off.
OR sets a bit when either value has a one there, which is how you turn individual bits on.
XOR sets a bit when the two values differ there, so it flips bits that are one in only one operand.
They are the AND and OR results with every bit flipped, so NAND clears a bit whenever both inputs are one.
NOT flips every bit of the first value across the chosen width, so the second value is ignored.
The bits above the chosen width are dropped, so flipping 45 at 8 bits gives a different pattern from flipping it at 32 bits.
Each row is one bit position showing both input bits and the outcome for every operation, so you can check the logic.
Yes. Enter a minus sign and the value is held in twos complement form at the chosen width.
It gives both the unsigned value and the signed twos complement reading of the result.
Yes. The calculation is local, free and never sends your values anywhere.
