XOR Calculator
Bitwise XOR two hexadecimal values and get the hex result.

What does an XOR calculator do?
An XOR calculator performs a bitwise exclusive-or on two hexadecimal values, setting each output bit only when the two input bits differ. Snabbit parses each operand (0x optional), XORs them, and shows the result in hex, so 0xFF XOR 0x0F gives 0xF0. It runs in your browser, so the values you combine stay private.
How to use the XOR Calculator
- 1 Enter the first hex value in field A (0x optional).
- 2 Enter the second hex value in field B.
- 3 The bitwise-XOR result appears instantly in hex.
- 4 Copy the result.
What you can use it for
- Computing a simple XOR checksum or parity bit.
- Toggling specific bits between two values.
- Demonstrating one-time-pad style XOR ciphers.
- Comparing two registers bit by bit.
Frequently asked questions
What does XOR return?
XOR sets a bit to 1 only when the two input bits differ. Equal bits become 0, so a value XORed with itself is always zero.
Why is XOR useful?
XOR underpins simple ciphers, checksums and parity, and is a quick way to toggle or compare specific bits between two values.
Can I XOR values of different sizes?
Yes. Operands are parsed as numbers first, so a one-byte value and a two-byte value XOR correctly. Invalid hex leaves the result blank.
