FAQ
Is the original order preserved?
Yes — the first occurrence of each line is kept in place; later duplicates are removed.
Does case matter?
By default yes. Toggle case-insensitive to treat 'Apple' and 'apple' as duplicates.
Does empty lines get deduped?
Empty lines count as duplicates too, so only one blank line remains.
