Bitwise Calculator
Run AND, OR, XOR, NOT and bit shifts on two numbers
Apply AND, OR, XOR, NOT, left shift and right shift to two 32-bit integers, with the result shown in decimal, hexadecimal, octal and binary. Everything runs locally in your browser.

What this tool does
Bitwise operators work on the individual bits of a number rather than its value as a whole, which is why they show up constantly in flags, permissions, color channels and low-level protocols. This calculator takes two whole numbers, applies the operator you pick, and treats the result as an unsigned 32-bit value so the decimal, hex, octal and binary readouts always line up with what a language like JavaScript, C or Python would print.
How to use it
- Enter value A, and value B if the operation needs it.
- Pick an operation: AND, OR, XOR, NOT, or a left/right shift.
- Read the result in decimal, hex, octal and binary.

Frequently asked questions
- Why is NOT of a small number a huge one?
- NOT flips every bit, and this tool displays the result as an unsigned 32-bit number, so NOT of a small positive value comes out close to 4,294,967,295.
- How do the shift operators work?
- A left shift moves A's bits toward the high end by B positions (multiplying by 2 per shift); a right shift moves them toward the low end (dividing by 2 per shift, discarding remainders).
- Is anything uploaded?
- No. The numbers and result are computed in your browser.
