Remove Empty Lines
Remove empty lines and blank lines from text instantly. Option to also remove whitespace-only lines. Free online tool, client-side processing.
Why Use the Remove Empty Lines Tool?
Empty and blank lines clutter text files, increase file size, and can cause issues in data processing. Whether you're cleaning up code, preparing data for import, or formatting documents, our tool removes unwanted blank lines with a single click.
Key Features
- Remove completely empty lines (zero-length lines)
- Optional removal of whitespace-only lines (lines with only spaces/tabs)
- Real-time statistics: total lines, removed, remaining
- Side-by-side input/output view for easy comparison
How to Use
- Paste your text with empty lines in the input area
- Toggle the 'Remove whitespace-only lines' option if needed
- Copy the cleaned result from the output area
Technical Details
The tool splits text by newline characters and filters lines based on the selected criteria. Empty lines (zero length) are always removed. When whitespace-only removal is enabled, lines containing only spaces, tabs, or other whitespace are also filtered. The tool preserves all non-empty line content exactly as provided.
FAQ
What's the difference between empty and whitespace-only lines?
An empty line has zero characters (just a newline). A whitespace-only line contains only spaces, tabs, or other invisible characters but no visible content.
Will this remove indentation from my code?
No. Lines with actual content (even just a space before text) are preserved. Only lines that are completely empty or contain only whitespace characters are removed.
