About Remove Empty Lines
Remove Empty Lines is a text cleanup tool that strips blank lines from any block of text. Whether you are tightening a document's spacing, cleaning up copied code, or preparing data for processing, this tool removes all empty lines instantly — leaving only lines that contain actual content.
When you copy text from web pages, PDFs, or emails, it often arrives with excessive blank lines — sometimes three or four between paragraphs. These gaps create an unprofessional appearance in documents and can cause formatting issues in code and data files. The Remove Empty Lines tool eliminates them all in one pass.
The tool includes a 'trim whitespace' option (enabled by default). When on, lines that contain only spaces, tabs, or other whitespace characters are also removed — not just truly empty lines. This catches the common case where a line appears blank but actually contains invisible characters that can cause problems in data processing.
Developers use the tool to clean up code files. Extra blank lines between functions, classes, or statements can make code harder to read and navigate. Removing them creates tighter, more professional code. It is also useful for cleaning up JSON, XML, and CSV files where empty lines can cause parsing errors.
Data analysts use the tool to prepare data for import. Empty lines in CSV files can create null rows that break database imports. Empty lines in log files can disrupt parsing scripts. By removing them first, you ensure clean, continuous data that processes without errors.
Writers and editors use the tool to tighten documents. Excessive blank lines between paragraphs create a disjointed reading experience. Removing them creates a clean, consistent flow. The tool preserves all content lines exactly as they are — only blank lines are removed.
A counter shows how many empty lines were removed, giving you confidence in the cleanup. All processing is client-side — your text never leaves your browser. There are no limits, no signups, and no cost.

Frequently Asked Questions
What counts as an 'empty line'?
A line with zero characters. If 'trim whitespace' is on, lines containing only spaces, tabs, or other whitespace are also treated as empty.
Does it remove spaces between words?
No. Only entirely blank lines (or whitespace-only lines) are removed. Content within non-empty lines is preserved exactly.
Can I remove blank lines from a very long document?
Yes. The tool handles large texts with no performance issues.
Is my text uploaded to a server?
No. All processing happens locally in your browser. Nothing is stored or transmitted.
Is Remove Empty Lines free?
Yes, completely free with no registration required.
