Remove Line Breaks Online

Updated 2026-07-09

Remove line breaks from text online for free. Paste multi-line text and SnapTools joins it into a single line, replacing each break with a space or any separator you choose — instantly, in your browser. Nothing is uploaded.

Hard line breaks copied from PDFs, emails, or wrapped code comments turn a clean paragraph into a jagged mess. This tool joins those lines back together, handling both Windows and Unix line endings, and lets you pick what goes in each break's place — a space to keep words readable, nothing to concatenate values, or a comma to build a list.

// how to use

1 Paste multi-line text into the input panel on the left.
2 SnapTools joins the lines into one, replacing each break with a space (or a string you choose).
3 Read the single-line result on the right, then copy or download it.

// faq

No. The operation runs entirely in your browser, so your text never leaves your machine.

By default a single space, so words do not run together. You can change the replacement to an empty string, a comma, or any custom separator to suit your target format.

Yes. Both carriage-return/line-feed (Windows) and line-feed (Unix/Mac) breaks are recognised and removed, so mixed-ending text joins cleanly.

This specifically joins lines by removing newlines. The Whitespace Remover focuses on spaces and tabs, and only strips line breaks in its most aggressive mode.

It removes the line breaks themselves. If you only want to reduce runs of empty lines while keeping the rest of the structure, use Remove Extra Blank Lines instead.
