How to remove or add line breaks in text

Text often arrives with unwanted line breaks—whether you're reformatting code, cleaning up pasted content, or preparing data for processing. Removing or consolidating these breaks instantly makes your text more usable.

Why line breaks cause problems

Line breaks inserted automatically by text editors, email clients, or web forms often don't align with your actual needs. A paragraph might be split across multiple lines when you need it as a single continuous string. Pasted content frequently arrives with extra spaces, empty lines, or stray breaks that clutter the data.

Removing unwanted line breaks

The fastest way to strip all line breaks from text is to use the Remove line breaks tool. It converts multi-line text into a single continuous string in one pass, handling both standard line feeds and carriage returns. This approach works for any content: paragraphs, CSV data, code snippets, or formatted lists.

Combining lines efficiently

When you need more control over which lines merge together, the Combine lines tool lets you join lines with a custom separator. Instead of simply removing breaks, you can specify what goes between joined lines—a space, a comma, a pipe character (|), or nothing at all. This is useful for reformatting lists, preparing data for processing, or restructuring output.

Cleaning up empty lines and whitespace

Excess empty lines are as problematic as unwanted line breaks. Use the Remove empty lines tool to strip all blank lines and get clean, compact output. For more targeted cleanup, the Trim lines tool removes leading and trailing whitespace from each line, preserving structure while eliminating padding that wastes space or causes alignment issues.

Privacy and local processing

All line-break adjustments happen directly in your browser. Text never leaves your device, there's no upload step, and the tools work offline after the initial page load. No account, no tracking, no server processing—just instant, private text manipulation.

Common workflows

Developers often need to remove line breaks when preparing minified data or reformatting API responses. Content writers remove them when copying text from formatted sources. Data analysts use these tools to clean up spreadsheet exports before processing. The technique is quick enough to use dozens of times daily without friction.
