Duplicate Remover

It removes duplicate lines from your text, helping you clean up lists, logs, or any line‑based data. You can also ignore case, trim whitespace, remove blank lines, and sort the output.

When enabled, lines that differ only in letter case (e.g. 'Hello' and 'hello') are treated as duplicates and only one of them is kept.

It removes leading and trailing whitespace from each line before comparing them. This helps when your text has inconsistent spacing.

Yes. Use the 'Sort order' dropdown to sort the unique lines alphabetically in ascending or descending order.

No. All processing is done locally in your browser. Your text never leaves your device.
