Remove Empty Lines
Delete blank lines from your text instantly. Choose to remove completely empty lines, or also strip lines that contain only spaces or tabs. Perfect for cleaning messy logs, code, or copied text. No signup, no uploads — everything runs right in your browser.
Why use this Remove Empty Lines tool?
Empty lines can make text look untidy, waste space in documents, or break formatting when imported into other applications. This tool quickly cleans up your text by stripping out those unnecessary blank lines. You can choose to remove lines that are completely empty, or also take out lines that contain only invisible whitespace characters.
- Two removal modes – delete truly empty lines, or also delete lines with only spaces/tabs.
- Keeps content intact – lines containing any visible text are never affected.
- Instant preview – the output updates as you type (with a short delay) or when you click the button.
- 100% private – processing happens locally in your browser; your text never leaves your device.
How to remove empty lines (step‑by‑step)
1. Paste your text
Copy any block of text that contains unnecessary blank lines and drop it into the left box.
2. Choose removal mode
Check "Remove whitespace‑only lines" to delete lines that appear empty but contain spaces or tabs. Uncheck to keep them.
3. Get cleaned text
The result appears on the right with all empty lines stripped away. Your content is now compact and tidy.
4. Copy or download
Use the buttons to copy the cleaned text to clipboard or save it as a .txt file.

Common use cases
- Code cleanup: Remove unnecessary blank lines from source code to make it more compact.

Pro tips
- If you only want to remove lines that are completely empty (zero characters), uncheck "Remove whitespace‑only lines". This preserves lines with intentional indentation.
- After removing empty lines, you can further polish your text with Whitespace Cleaner or Text Cleaner.
- For code, this tool is great before minification or when you want to reduce file size by removing blank lines.
- The tool preserves line endings – only empty lines are removed, not the line breaks between non‑empty lines.
