Frequently Asked Questions
Is the text duplicate remover really free?
Yes, our text duplicate remover is completely free to use with no hidden costs, watermarks, or usage limits. All processing happens in your browser, so there are no server costs or API fees.
What removal modes are available?
Our tool supports three removal modes: lines (removes duplicate lines), words (removes duplicate words), and paragraphs (removes duplicate paragraphs). You can choose the mode that best fits your needs.
Can I keep the first or last occurrence of duplicates?
Yes! Our tool includes three keep modes: keep first (keeps the first occurrence and removes subsequent duplicates), keep last (keeps the last occurrence and removes previous duplicates), and keep all (keeps all occurrences but marks them as duplicates).
Does it work with large texts?
Yes, our tool can handle large texts efficiently. However, for very large texts (over 100,000 lines), the processing may take a few seconds. All processing happens in your browser, so your text is never uploaded to any server.
Can I ignore case or whitespace when comparing?
Yes! Our tool includes flexible comparison modes: exact match (compares exactly as written), ignore case (treats uppercase and lowercase as the same), ignore whitespace (ignores spaces and tabs), or ignore both (ignores both case and whitespace). This is useful for cleaning data where formatting differences are not important.
