🧹 Duplicate Line Remover
Clean up messy lists: drop duplicates, sort lines, trim spaces and remove blanks.
How to use
- Paste your list — one item per line.
- Tick the options you want (dedupe, sort, trim and more).
- Click Clean lines, then copy the result.
FAQs
Which duplicate is kept?
The first occurrence of each line is kept and later repeats are removed, so your list's original order is preserved unless you also tick "Sort lines".
What does "Ignore case" do?
With it ticked, "Apple" and "apple" count as the same line. Without it, they are treated as different lines.
Can I process very long lists?
Yes — everything runs locally in your browser, so even lists with tens of thousands of lines are handled instantly.
