About this tool
The tool keeps the first time each line appears and removes later repeats, without re-sorting, so your list stays in the order you gave it. The status line tells you how many lines were removed.
Turn on “Ignore upper/lower case” to treat Apple and apple as the same, and “Trim spaces” to catch copies that differ only by a trailing space. Useful for email lists, keyword research, product codes, attendance sheets and log files of any size.
Everything runs in your browser. Your text is never uploaded or stored, so it is safe for drafts, code and private documents.
हिंदी में मदद
सूची में दोहराई गई लाइनें हटाएँ। हर लाइन का पहला रूप उसी क्रम में बचा रहता है। बड़े-छोटे अक्षर और फालतू स्पेस को नज़रअंदाज़ करने का विकल्प भी है।
Questions
Does it change the order of my list?
No. Lines stay in their original order; only the later copies are removed. Use Sort lines afterwards if you want them alphabetical.
Are blank lines removed?
Only if you tick “Remove empty lines”. Otherwise blank lines are kept so paragraph spacing survives.
Can it handle a very long list?
Yes. Lists with hundreds of thousands of lines are processed in a fraction of a second on a normal laptop or phone.
