Remove Empty Lines

Remove Empty Lines is a free online text cleaning tool that strips blank lines, whitespace-only lines, and excessive spacing from any text. It's the fastest way to clean up pasted content, code output, log files, or documents that have accumulated extra line breaks.

Beyond basic removal, the tool offers squeeze mode (collapse multiple blanks into one), a configurable limit on consecutive blank lines, per-line trimming, pattern-based line removal, and the option to add consistent spacing between sections. Everything runs locally in your browser.

• Remove all empty lines: Strip every blank line in one click
• Include whitespace-only lines: Also remove lines containing only spaces or tabs
• Squeeze blank lines: Collapse consecutive blanks into a single blank line
• Limit consecutive blanks: Set a maximum number of allowed consecutive blank lines (1, 2, 3…)
• Trim lines: Remove leading and trailing whitespace from every line
• Remove lines by pattern: Delete any line containing a specific string or matching a regex
• Remove lines NOT matching pattern: Keep only lines that contain a specific pattern
• Add line breaks: Insert a blank line after every N lines for readability
• Live statistics: Input lines, output lines, empty lines removed, whitespace lines removed
• 100% client-side: Private, instant, no server processing
