Remove Line Breaks from Text

What Is This Tool?

This tool removes line breaks (newlines / "Enter" characters) from pasted text and joins everything into a single line. It handles all common line-ending formats — Unix (\n), Windows (\r\n), and old Mac (\r) — so text copied from any source works correctly.

You control what fills the gap where each line break used to be: a single space (the usual choice for turning wrapped paragraphs back into flowing text), nothing at all (for directly concatenating fragments), or a custom separator like a comma or pipe character (useful for turning a pasted list into a delimited string).

Why Use It?

• Handles Windows, Unix, and old Mac line endings correctly.
• Three replacement choices: space, nothing, or a custom separator.
• Empty lines are skipped automatically so you don't get doubled separators.
• Local processing — text never leaves your browser.
• No sign-up, no character limit, free to use.

How to Use

1. Paste your multi-line text into the input box.
2. Choose what should replace each line break: a space, nothing, or a custom separator.
3. Click Remove Line Breaks.
4. Copy the single-line result.

Example

Input

Line one
Line two
Line three

Output

Line one Line two Line three

With "A space" selected, each line break is replaced by a single space, so the three lines merge into one continuous line of text.

Common uses

• Flattening a multi-line address or note into one line for a CSV field.
• Turning a pasted list into a comma- or pipe-separated string for code or a database query.
• Joining wrapped paragraph text (copied from a PDF, where every line break is a mid-sentence artifact) back into flowing prose.
• Preparing text for systems that don't accept literal newline characters in a single input field.
