How to use Right-pad Integers
- 1. Paste your integers. Enter the integers you want padded, one per line or separated by whitespace, regardless of how many digits each already has.
- 2. Set the target width. Enter Target width to define how many characters each integer should occupy after padding, such as 5 to turn 42 into a five-character string.
- 3. Choose the fill string. Enter Fill string to control what character fills the gap, such as 0 or a space, applied after the integer's existing digits.
- 4. Copy the padded integers. Copy the resulting list, where every integer has been extended on the right to match your target width using the chosen fill.
When to use Right-pad Integers
Right-pad Integers extends each number with a fill character on the right until it reaches a fixed width, unlike left-padding which fills before the digits. Use Right-pad Integers whenever trailing characters, rather than leading ones, need to bring numbers to a consistent length.
- Formatting fixed-width fields for a legacy export. An older file format expects every numeric field to occupy an exact character width, padded with trailing characters rather than leading zeros.
- Building a byte-count or offset table. You are documenting binary offsets that need to appear as fixed-width values with trailing padding so a following column of labels stays aligned.
- Creating placeholder codes with a fixed length. You need short numeric codes extended to a specific total length with trailing zeros or spaces, useful for mocking up ID formats in a demo.
- Testing a right-pad string function. You wrote code that pads numeric strings on the right and want a trusted reference output for several widths and fill characters to compare against.

About the Right-pad Integers tool
Right-pad Integers does its work locally, right in the browser. Pad integers on the right up to a fixed width. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the Integer Tools collection on EditSafely, a set of 133 small, focused Integer utilities that share the same instant, private workspace.
You can shape the output with 2 settings, including Target width and Fill string, 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.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
Frequently asked questions
Is Right-pad 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.
