• Remove blank lines: Deletes every line that is empty or contains only spaces/tabs.
• Merge blank lines: Turns multiple consecutive blank lines into a single one. Great for cleaning up log files or exported reports.
• Trim each line: Strips leading and trailing whitespace from every line, but keeps inner spaces intact.
• Trim top/bottom blanks: Removes blank lines and whitespace from the very start and end of the whole text.

FAQ

• Q: Does "Remove blank lines" also strip spaces from non-blank lines?
  A: No, it only deletes lines that are fully empty or contain nothing but whitespace. Content lines stay exactly as they are.
• Q: What is the difference between "Merge blank lines" and "Remove blank lines"?
  A: Merge keeps one blank line between paragraphs (great for readable text), while Remove deletes every blank line. You can run them in sequence — Merge first, then Remove — for the combined effect.
• Q: Does it handle all three line-ending styles?
  A: Yes — \r\n (Windows), \n (Unix/Linux/macOS) and \r (old Mac) are all recognised and normalised to \n internally.
