Remove Duplicates

Paste any list and remove duplicate lines instantly. Choose whether matches are case-sensitive, keep the first or last occurrence, trim extra spaces, drop blank lines, and optionally sort the result. Everything runs locally in your browser.

Input (one item per line)

Lines: 0

Output

0 lines • 0 removed

Case-sensitive (treat Apple ≠ apple) Trim whitespace on each line Remove blank / whitespace-only lines Sort result (A → Z) Keep last occurrence (unchecked = keep first) Collapse multiple spaces to one

How it works

Duplicates are detected per line, after applying the options you choose.
Keep last occurrence lets later lines override earlier ones.
Sorting is applied after deduplication.
Everything runs locally; nothing is uploaded.
