Frequently Asked Questions

Remove All Empty deletes every blank line, so all your content lines are packed together with no gaps. Collapse Multiple is gentler — it reduces any run of 2+ consecutive blank lines down to a single blank line, preserving intentional paragraph spacing while removing excessive gaps.

Lines that contain only spaces, tabs, or other invisible characters. They look blank but aren't technically empty strings. The "treat whitespace-only lines as empty" option catches these so they're treated the same as truly empty lines during processing.

Common use cases: cleaning up code exported from IDEs that add extra blank lines, removing extra whitespace from copied text or CSV data, preparing text for systems with line limits, cleaning up log files, and formatting content for tight layouts like social media posts.
