Duplicate Line Remover FAQ
Which lines are kept as duplicates?
The first occurrence of each line is kept; subsequent identical lines are removed as duplicates.
Are empty lines treated as duplicates?
Yes. Empty lines are unique entries, so multiple empty lines will be deduplicated to a single empty line.
Is my text processed locally?
Yes. All deduplication runs in your browser; your text never leaves your device.
