What this tool does

A focused tool for a specific cleanup job

Remove Empty Lines distinguishes truly empty lines from lines containing spaces or tabs. You can remove every blank or collapse repeated blank runs into one deliberate separator.

Common use cases

  • Clean data copied from PDFs
  • Repair lists with accidental blank rows
  • Normalize article paragraph spacing
  • Prepare plain text for import

How to use Remove Empty Lines

  1. Paste the text with unwanted gaps.
  2. Choose whether whitespace-only lines count as empty.
  3. Remove all matching lines or collapse runs to one.
  4. Review paragraph spacing and copy the result.

Options explained

  • Whitespace-only detection includes spaces and tabs.
  • Collapse mode leaves one empty line between text blocks.
  • Preserve paragraph breaks is useful for prose, while full removal is better for lists.

Edge cases and limitations

  • Line endings are normalized in the output.

Can I keep one blank line between paragraphs?

Yes. Choose collapse mode to reduce each run of blanks to one empty line.

They are when whitespace-only lines are treated as empty.
