Frequently asked questions

Does removing duplicates keep order?

If sorting is off, the first occurrence of each line is kept in its original position. Turn on sorting to order the result alphabetically.

Is the matching case-sensitive?

By default yes. Toggle 'Ignore case' to treat lines that differ only in capitalization as duplicates and to sort case-insensitively.

Is my text uploaded?

No — all processing happens locally in your browser.
