How to use Truncate Binary Values
- 1. Paste your binary value. Enter a binary number into the input pane, such as a wider field you want narrowed down to a specific bit width for a comparison.
- 2. Set the Keep length. Choose how many bits should remain after truncation, matching whatever fixed width your target field, register or format requires.
- 3. Choose Drop bits from and copy. Pick Start to drop leading bits and keep the tail, or End to drop trailing bits and keep the head, then copy the shortened result.
When to use Truncate Binary Values
Truncate Binary Values shortens a binary number to a fixed length by dropping bits from either end, useful whenever a value needs to fit a narrower field than it currently occupies. Use it to test how a value fits before writing the logic yourself.
- Fitting a value into a narrower register. You have a 16-bit value that needs to be stored in an 8-bit register and want to see exactly what remains after dropping the extra leading bits.
- Testing overflow behavior for a fixed-width field. You are debugging a protocol where a field is defined as a specific bit width and want to check what happens when a wider value gets truncated.
- Trimming a padded value back to its real length. You padded a bit string earlier and now need to remove the padding from one end to recover the original, unpadded binary value.

About the Truncate Binary Values tool
Truncate Binary Values is a free online tool that works entirely inside your web browser. Drop leading or trailing bits and make a binary value shorter. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 112 Binary utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with 2 settings, including Keep length and Drop bits from, and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
Frequently asked questions
Does Truncate Binary Values 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.
