Good to know
Duplicate Line Remover Online keeps the first copy of each line, removes later duplicates, and can drop blank lines in the same pass. The readout reports the number of duplicate lines removed and the number of blank lines dropped as separate figures.
Frequently asked questions
Does it remove blank lines too?
Yes. With the drop-blank option on, empty lines are removed alongside the duplicate lines.
Are the two counts separate?
Yes. The readout shows duplicates removed and blank lines dropped as distinct numbers.
Can I keep blank lines if I want?
Yes. Turn off the drop-blank option and empty lines are preserved while duplicates are still removed.
