Frequently Asked Questions
Everything you need to know about the Bitwise Calculator.
What operations does this support?
AND, OR, XOR, NOT, NAND, NOR, and left/right bit shifts.
Can I enter numbers in hex or binary?
Yes, decimal, hex (0x), and binary (0b) input are all supported.
Is it free?
Completely free, no sign-up or limits.
What does the bit-width setting do?
It sets how many bits NOT and shift operations operate on (8/16/32-bit), affecting sign extension and wraparound.
How are negative numbers handled?
Via two's complement at the selected bit width, explained inline.
Does it show the binary working?
Yes, both operands and the result are shown as aligned bit columns.
What happens if I shift by more than the bit width?
It's flagged with a clear message rather than giving a silently wrong result.
Is the result also shown in decimal and hex?
Yes, all three formats are shown together.
Is my data stored?
No; everything runs in your browser.
Does it work on mobile?
Yes, fully responsive with no overflow.
