Remove Duplicate Lines
Remove duplicate lines from text or lists online for free. Keep the first occurrence, ignore case or trim spaces, and copy the unique lines.
Frequently asked questions
- Which duplicate is kept?
- The first occurrence of each line is kept and later repeats are removed, so the original order of your list is preserved.
- Can it treat lines with different capitalization as duplicates?
- Yes. Turn on 'Ignore case' and lines like 'Apple' and 'apple' are treated as the same line.
- Is my list uploaded anywhere?
- No. Deduplication runs entirely in your browser — your text never leaves your device.
