Remove duplicate lines from any list
Paste a list — emails, URLs, keywords, log lines — and every repeated line is removed instantly while the original order is kept. Choose whether "Apple" and "apple" count as the same line, whether surrounding spaces matter, and whether to keep the first or the last copy of each duplicate.
Is there a size limit?
No hard limit — hundreds of thousands of lines are processed in milliseconds, entirely in your browser.
