What is Remove Empty Lines?
Empty lines are lines that contain no visible characters — either completely empty or containing only spaces and tabs. Removing empty lines cleans up text for data processing, code formatting, log analysis, and preparing content for import. This tool lets you choose whether to remove completely empty lines, whitespace-only lines, or both.

Frequently Asked Questions
What is the difference between empty and whitespace-only lines?
A completely empty line has zero characters (just a newline). A whitespace-only line contains only spaces, tabs, or other whitespace characters — no visible content. Both appear as blank lines in a text editor.
Will this affect my line numbers?
Yes. Removing lines changes the total line count and renumbers all subsequent lines. If you need to preserve line numbers, consider replacing empty lines with a placeholder instead.
Can I undo the removal?
The tool processes text in real time but does not modify your original input. Your original text remains in the input area. Click Clear to reset both panels.
