Remove Duplicate Lines

Delete repeated and duplicate lines from any text, keeping only unique lines

Free · Instant · Private — runs in your browser

How the Remove Duplicate Lines works

Paste a list or block of text and the Remove Duplicate Lines tool scans it line by line, keeping only the first occurrence of each line and discarding the rest. You can choose whether the comparison is case-sensitive and whether to ignore leading and trailing whitespace, so “Apple ” and “apple” can be treated as the same or different depending on your needs.

The deduplication runs entirely in your browser, so lists of any size are processed instantly and privately. After removing duplicates, use Sort Lines to order the remaining entries, or Text to List to format them with bullets or numbers.
