Explain Each Type

To give you full control, the tool offers a few nuanced options:

• Remove Duplicate Lines
  The primary function scans all lines and eliminates any repeats, preserving only the first occurrence. Ideal for cleaning lists, logs, or any multi-line text.
• Case-Sensitive vs. Case-Insensitive
  Optionally, you can choose whether the tool treats “Apple” and “apple” as duplicates. Case-sensitive mode keeps them distinct; case-insensitive mode removes repeats regardless of capitalization.
• Trim Before Comparison
  Enabling this ensures leading and trailing spaces are ignored during duplicate detection, so lines that differ only by whitespace are treated as the same.

These options let you tailor the Duplicate Line Remover Online experience to your precise needs.
