How to use AND Integers
- 1. Paste the integers to AND. Enter two or more integers separated by spaces, commas or newlines. Each is converted to its binary representation before the bitwise operation runs.
- 2. Read how the AND combines them. The tool ANDs every integer together bit by bit, so a result bit is 1 only where the corresponding bit is 1 in all of the inputs. There are no settings to configure.
- 3. Copy the resulting integer. Copy the combined decimal result and paste it into your code, notes or bug report. Compare it against what your program's own bitwise AND produced.
When to use AND Integers
AND Integers performs a bitwise AND across a list of whole numbers and returns the combined result, without you needing to open a REPL or write a throwaway script. It is aimed at anyone debugging flags, masks or low-level logic by hand.
- Debugging a permissions bitmask. A Unix-style permission value and a mask need to be ANDed to check which bits survive. Paste both integers in and confirm the result matches what your access-control code expects.
- Verifying a hardware register calculation. Embedded firmware code ANDs a status register against a flag constant to test a condition. Reproduce the same operation here to confirm the expected bit pattern before trusting the device.
- Checking feature flag combinations. An application encodes enabled features as bits in an integer. AND two flag values together here to see which features are common to both without writing a script.
- Teaching bitwise operators. Explaining how AND differs from OR is easier with a working example a student can try their own numbers in, rather than tracing through binary by hand every time.

About the AND Integers tool
AND Integers runs as plain JavaScript in your browser tab, with no server behind it. Bitwise-AND a list of integers together. Whatever you put in stays on your device from start to finish.
The tool is part of EditSafely's Integer Tools section, 133 single-purpose utilities built around the same idea: open the page, get the result, keep your data to yourself.
There is nothing to configure. Provide the input and the result appears on its own. 2 worked examples further down the page show exactly what the tool produces for real inputs.
That local-first design has practical benefits beyond privacy. The tool keeps working on a flaky connection once the page has loaded, results are instant because nothing round-trips to a server, and it is safe to use with confidential material.
Frequently asked questions
Does AND Integers cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
