How it works
- Enter two hexadecimal values.
- Choose an operation: add, subtract, multiply, divide, or a bitwise AND/OR/XOR.
- The result shows in hex, decimal, and binary.
The formula
Each hex value is converted to decimal, the operation is applied, then the result is converted back:
0x1A + 0x2F = 26 + 47 = 73 = 0x49
FAQ
Do I need to type "0x" before my hex values?
No — it's optional. "1A" and "0x1A" both work.
Can the result be negative?
Yes, for subtraction where the second value is larger — the result shows a leading minus sign.
What do AND, OR, and XOR do?
They perform bitwise operations on the two values' binary representations, useful for low-level programming and flag manipulation.
Is my data sent anywhere?
No — every calculation happens locally in your browser.

Your OS calculator's programmer mode can do this too, but it's buried behind a mode switch. Hex Calculator is one page, always in the right mode.
