How to remove empty lines
- Paste your text into the input box. Empty lines are removed instantly as you type or paste.
- Choose a mode — Remove all deletes every blank line, or Collapse reduces multiple consecutive blank lines to a single one while keeping paragraph spacing.
- Toggle Trim lines if your text has lines that look blank but contain hidden spaces or tabs — this strips them before processing.
- Copy the output using the copy button at the top of the output panel.
When to remove empty lines
Cleaning up copied text
Text pasted from PDFs, websites, or documents often includes extra blank lines. Remove them to get clean, compact output.
Preparing data for import
Many CSV parsers, spreadsheet imports, and database tools fail on blank rows. Strip them before uploading.
Code formatting
Style guides like PEP 8 (Python) allow at most two blank lines between top-level definitions. Collapse mode enforces consistent spacing.
Email and newsletter copy
Copying from a doc often adds triple-spaced gaps between paragraphs. Collapse to single blank lines before sending.
Log file cleanup
Log files with blank separators between entries can be compacted with collapse mode for easier reading and analysis.
Template and config files
Config files and templates with accidental extra blank lines can cause parsing issues. Remove all to be safe.
Remove all vs. Collapse
Remove all is the right choice when blank lines serve no purpose — data files, code lists, single-column imports, or any context where whitespace between lines is noise.
Collapse is better when blank lines carry meaning — like paragraph breaks in prose or section separators in config files — but the text has accumulated extra spacing over time from multiple edits or copy-pastes. Collapse keeps one blank line between sections while removing the extras.
