How to use Truncate Integers
- 1. Paste your integers. Enter one or more integers, such as 12345, one per line or separated by spaces. Each value is shortened independently by the same rule.
- 2. Set how many digits to drop. Choose How many digits to drop for the count of digits to remove from each integer, for example dropping 2 from 12345 leaves 123.
- 3. Choose which end to drop from. Set Drop from to End to remove digits from the right, the common choice for rounding down to a coarser precision, or Start to remove leading digits instead.
- 4. Copy the truncated result. Copy the shortened integers and use them wherever a coarser or trimmed version of the original numbers is needed.
When to use Truncate Integers
Truncate Integers shortens whole numbers by chopping off a set number of digits from either end, without rounding. It is for reducing precision or trimming padded values quickly, when a full rounding calculation is more than you need.
- Coarsening a precise measurement. A sensor logs readings as long integers like 12345 but a report only needs the leading digits. Dropping the last two digits from the end gives a quick, coarser value.
- Trimming padded IDs. A system generates IDs with extra trailing digits appended for internal use. Truncating those digits from the end recovers the shorter ID a human actually needs to reference.
- Removing a leading prefix code. An integer has a fixed-length prefix code stuck on the front, such as a region or batch number. Dropping digits from the start strips the prefix and leaves the real value.
- Estimating an order of magnitude. You want a rough sense of scale for a large integer without full rounding logic, so truncating trailing digits gives a quick approximate value to compare against others.

About the Truncate Integers tool
Truncate Integers runs as plain JavaScript in your browser tab, with no server behind it. Drop digits to make integers shorter. 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.
You can shape the output with 2 settings, including How many digits to drop and Drop from, and the result refreshes the moment you change one. 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
Is Truncate Integers free to use?
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?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
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?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
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.
