About Duplicate Line Remover
Remove duplicate lines from a list, with options to trim whitespace, ignore blank lines and sort. Everything runs locally in your browser; nothing is uploaded. Only the current result is shown — no history or side-by-side comparison.
Duplicate Line Remover reads “Paste your list” from the form above and writes the answer into the results panel. There is no account, no upload and no server round-trip: the JavaScript on this page does the work on your own device.
How to use Duplicate Line Remover
- Open Duplicate Line Remover from Text & Code, or find it with the search box in the header.
- Fill in the fields shown above: “Paste your list”.
- Press Process. The result replaces whatever was shown before; only the current run is displayed, never two results side by side.
- Use Copy to put the result on your clipboard. A message appears only when something was actually copied.
A worked example
Enter your own values in the fields above and press Process. Change any input and press again; the result is recalculated from the current inputs and replaces the previous one.
Frequently asked questions
Is what I type uploaded anywhere?
No. Duplicate Line Remover processes “Paste your list” with JavaScript inside your browser. Your inputs and the result stay on your device; Utilixo keeps no copy of them.
Can I keep several results to compare?
No. Each press of Process rebuilds the result from the current inputs and overwrites the previous one. To compare runs, note the earlier result down yourself.
Anything specific to watch with Duplicate Line Remover?
The result depends only on the fields shown above (“Paste your list”); change one of them and press Process again to get an updated answer.
How do I take the result away?
Press Copy after a result appears. The copy button only reports success when there is content to copy.
Do I need to sign up or pay?
No. Duplicate Line Remover is free, needs no registration and has no usage limit. Open the page and use it.
