How to use Filter Integers
- 1. Paste your list of integers. Enter the integers you want to filter, separated by commas, spaces or newlines. Mixed formatting is fine since the tool splits on the separator you choose.
- 2. Pick the filter condition. Choose from Keep numbers that are, such as Greater than value, Even, Odd or Decimals. Each option defines a different rule the tool checks every number against.
- 3. Set the comparison value. For comparison-based filters, enter Value to compare against, such as 10 to keep numbers greater than 10. Parity filters like Even or Odd ignore this field entirely.
- 4. Copy the filtered results. Copy the surviving numbers from the output pane. Only the integers matching your condition remain, in the same order they appeared in the input.
When to use Filter Integers
Filter Integers keeps only the numbers in a list that satisfy a rule you pick, like greater than a threshold or strictly even. It saves you from manually scanning a column of numbers to decide which ones qualify. Use it whenever a dataset needs a quick numeric cutoff applied.
- Trimming outliers from survey data. A spreadsheet column of ages includes a few obvious data-entry errors like 999. Filter for values less than or equal to 120 to drop the impossible entries before analysis.
- Splitting even and odd IDs. A batch job needs to process even-numbered record IDs on one worker and odd ones on another. Run the ID list through the filter twice, once for Even and once for Odd.
- Finding values above a threshold. You copied sensor readings from a CSV and need only the ones above 15,000. Set the condition to Greater than value and 15000 to isolate the readings worth investigating.
- Separating integers from decimals. A pasted list mixes whole numbers and decimal measurements. Use the Integers or Decimals condition to split the two groups apart before running separate calculations on each.

About the Filter Integers tool
Filter Integers does its work locally, right in the browser. Find integers that match a filter (greater, less, equal). 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 3 settings, including Keep numbers that are, Value and Separator, 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 Filter 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.
