Bitwise Calculator
Bitwise Calculator is a browser-based calculator tool on CalcToolsBase. Free, browser-based Bitwise Calculator. Enter your input for an instant, clearly-labelled result - no signup, no uploads. To use it, enter your values and view the result directly in your browser — no signup and nothing to install.
Bitwise Calculator turns your first value, second value or shift amount and operation into the bitwise result in binary and decimal using AND, OR, XOR, NOT and bit shifts. The maths runs locally, so nothing you enter leaves the page.
Browser-side developer and utility helpers for everyday and learning use. Everything runs locally in your browser and nothing you enter is uploaded. Validate production or security-critical output with trusted, official tools before relying on it.
About this tool
With the Bitwise Calculator you can evaluate bitwise operations on integers in a few seconds. Supply your first value, second value or shift amount and operation and read the bitwise result in binary and decimal, computed via AND, OR, XOR, NOT and bit shifts. The tool is free, runs locally, and keeps every value on your machine.
How to use
- Enter the first whole-number operand.
- Enter the second value, or a shift amount for shifts.
- Pick the bitwise operation to apply.
- Read the result in decimal, binary, and hex.
Why use the Bitwise Calculator
Instant
Each result is computed on your device the moment you run the tool.
Private
The text and numbers you enter stay in your browser and are never uploaded.
Free
No signup and no paywall to use any tool in this set.
Works offline
Once the page has loaded it keeps working on a weak or dropped connection.
Built for developers
Plain inputs and outputs you can copy straight into code, configs, or notes.
Honest by design
Conversions and heuristics are for everyday and learning use; verify security-critical output with trusted, official tools.
Common uses
Bitwise when teaching binary and hex
Bitwise in bit-manipulation work
Bitwise when debugging binary data
Bitwise in firmware and driver tasks
Bitwise when converting between number bases
Bitwise before writing a bitwise expression
Technical notes
Bitwise Calculator applies the bitwise operators (AND, OR, XOR, NOT and shifts) to the integers bit by bit.
Results are reference values; validate against your own environment before relying on them in production.
Nothing you type is uploaded — the calculation happens entirely on your device.
Worked example
12 AND 10 = 1100 & 1010 = 1000 = 8; 12 OR 10 = 1110 = 14; 12 XOR 10 = 0110 = 6.
FAQ
How many bits does the calculator use?
Operations use 32-bit unsigned arithmetic, so results are shown as unsigned 32-bit values.
Does the NOT operation need a second value?
No. NOT inverts the bits of the first value only, so the second field is ignored for it.
What does the shift amount do?
For left and right shifts the second field is the number of bit positions to move, taken modulo 32.
Are negative inputs accepted?
Inputs are read as whole non-negative numbers and interpreted as 32-bit patterns before the operation runs.
