FAQ

Frequently Asked Questions

How does it detect duplicates?

Each non-empty line is compared case-sensitively (or case-insensitively if you enable that option) and duplicates are removed.

What if I want to keep the order?

The original order is preserved by default. Sorting is optional and only applied when you toggle it on.

Is it safe for large lists?

Yes, deduplication uses an efficient set, so it handles thousands of lines instantly in your browser.
