How do you remove duplicate lines online?
A remove duplicates tool deletes repeated lines from your list, keeping only the first occurrence of each and preserving the original order. Snabbit compares lines exactly, so identical entries collapse to one while everything else stays put. There is no upload step — the de-duplication runs entirely in your browser, so your data stays private.
How to use the Remove Duplicates
- 1 Paste your list, one item per line.
- 2 Identical lines are detected automatically.
- 3 Duplicates are removed, keeping the first of each, in order.
- 4 Copy the de-duplicated list.
What you can use it for
- Cleaning an email or contact list.
- Removing repeated rows from exported data.
- De-duplicating a list of URLs or keywords.
- Tidying merged lists before import.
Frequently asked questions
Which copy of a duplicate is kept?
The first occurrence is kept and later repeats are removed, so the order of your remaining lines matches the order they first appeared in the input.
Are near-duplicates with extra spaces removed?
Lines are compared exactly, so "apple" and "apple " (with a trailing space) count as different. Trim the text first if you want those treated as the same.
Does it sort the list?
No. De-duplication preserves your original order. If you also want the result sorted, run it through a line-sorting tool afterwards.
