What Is Remove Empty Lines?
Remove Empty Lines strips all blank lines from your text, leaving only lines that contain actual content. It can also treat whitespace-only lines (containing only spaces or tabs) as empty and remove those too.
This is useful for cleaning up code, data files, pasted content, or any text with excessive spacing. The output updates in real time as you type. This tool runs entirely in your browser — no text is sent to any server.

Features Explained
Whitespace-Only Line Detection
▼
When enabled (default), lines containing only spaces, tabs, or other whitespace characters are treated as empty and removed. Disable this to only remove truly blank lines with zero characters.
Real-Time Line Count
▼
The input and output labels show live statistics — total input lines, remaining output lines, and how many lines were removed. This gives you instant feedback on how much cleanup was done.
Preserves Line Content
▼
Only completely empty (or whitespace-only) lines are removed. All other lines are kept exactly as they are — no trimming, no modification, no reordering.
File Upload & Drag and Drop
▼
Upload a .txt file using the Upload button or drag and drop a text file directly onto the input area. Great for cleaning up large log files or data exports without manual copy-paste.
Who Is This Tool For?

Examples
| Input | Output | Removed |
|---|---|---|
| Line 1 / / Line 3 / / Line 5 | Line 1 / Line 3 / Line 5 | 2 blank lines |
| Hello / / / World | Hello / World | 2 blank lines |
| A / / B / / C | A / B / C | 2 whitespace-only lines |
| No blank lines here | No blank lines here | 0 lines |
/ represents a line break (Enter key) in the examples above. Spaces between slashes represent whitespace-only lines.
Tips for Removing Empty Lines
Whitespace-only detection is on by default
Lines with only spaces or tabs are removed by default. Uncheck the option if you want to keep whitespace-only lines and only remove truly blank ones.
Check the line count
The labels show exactly how many lines were removed. Use this to verify the cleanup matched your expectations.
Combine with other tools
After removing empty lines, use Sort Lines to alphabetize, Add Line Numbers to number them, or Remove Duplicate Lines to deduplicate.
Clean up code efficiently
Many code formatters leave extra blank lines. Paste your code here to quickly compress it before sharing or submitting.
Upload large files
For large log files or data exports, use the Upload button or drag and drop instead of pasting. The tool handles large files efficiently.
Non-destructive preview
Your original text stays in the input panel. The output panel shows the cleaned version side by side, so you can compare before copying.
