🧹 Remove Duplicate Lines — Deduplicate Text Online
Remove repeated lines — a clean list.
Have duplicate lines in a long list? Paste it — duplicates gone, only unique lines remain. It also tells you how many lines were removed.
How to Use?
- Paste your list (one item per line).
- Optionally turn on A–Z sort.
- Press Remove Duplicates and copy.
How It Works
Each line is kept only the first time it appears — later identical lines are removed. Empty lines are counted as lines too.
Frequently Asked Questions
Is it case sensitive?
Yes — 'Apple' and 'apple' are treated as different.
What about empty lines?
The first empty line stays, the rest are removed.
How many lines can it handle?
Thousands of lines easily — everything happens in the browser.
