Lists and pasted text often have one item per line when you need a single line or a custom separator. The Line Break Remover joins lines in the browser: remove line breaks and replace them with a space, nothing, or a custom separator—no sign-up and no data sent to a server.
What is the Line Break Remover?
The Line Break Remover is a free online tool that joins lines into one by removing line breaks. You can replace each break with a space, with nothing, or with a custom separator (e.g. comma or pipe). It is used to turn a list into one line, prepare CSV-like rows, or merge wrapped text from emails or PDFs. All processing runs in your browser; there is no upload, no storage, and no account required.
Key Features
- Replace with space, nothing, or custom — Choose how line breaks are replaced: space (words stay separated), empty string (no separator), or any character or string you enter.
- Unix and Windows line endings — Both LF (Unix) and CRLF (Windows) are handled. The tool treats them as line breaks regardless of OS.
- Instant result — Paste your text, set the separator, and see the joined line. Copy when ready.
- Privacy-first — All processing happens in your browser. Your text is never sent to any server.
- No size limit — Long text is supported in the browser. Paste as many lines as you need.
- Plain text — Works on any plain text. No formatting or HTML required.
How to Use the Line Break Remover
- Open the Line Break Remover tool.
- Paste or type your text (one item or phrase per line, if that is your structure).
- Choose what to replace line breaks with: space, nothing, or a custom separator (e.g.
,or|). - View the single-line (or custom-separated) result. Copy it.
- Paste into your document, CSV, or form. Use the "Use tool" button on the docs page if you are reading this from the documentation.
Real Use Cases
- List to one line — Turn a vertical list (e.g. keywords, tags, emails) into one line separated by space or comma for pasting into a form or meta field.
- CSV-like rows — Join lines with a comma or other delimiter to build a simple CSV row or pipe-separated line.
- Wrapped email or PDF text — Merge lines that were wrapped by the source into a single paragraph or line.
- Code and config — Flatten multi-line strings or config values into one line when required by format or API.
- Search and replace prep — Produce a single line so you can run one global replace in an editor.
- Social or meta fields — Paste a list of items and join with comma or space to fit a single-field limit.
Why Use the Line Break Remover Instead of Alternatives?
- vs. Manual join — No need to delete line breaks by hand or run multiple pastes. One paste, set separator, copy.
- vs. Find-and-replace in editor — Works in any browser. Handy when the text is in email, a web form, or another app.
- vs. Scripts — No coding. Anyone can join lines in seconds.
- vs. Typing in one line — Paste the list as-is and let the tool join with the separator you need.
The tool does one job—replace line breaks with a chosen separator—and does it reliably.
Benefits for Writers, Marketers, and Developers
- Writers — Merge wrapped paragraphs or turn bullet lists into one line for summaries or meta descriptions.
- Marketers — Convert keyword or tag lists into a single line for ads, meta tags, or CMS fields.
- Developers — Flatten multi-line input or config into one line for APIs, env vars, or command-line use.
Common Mistakes
- Output still has line breaks — Some sources use different line endings or invisible characters. Try pasting into a plain editor first, or use "replace with space" to see all joins clearly.
- Wrong separator — If you need commas between items, choose a custom separator (e.g.
,). "Nothing" joins with no character between lines. - Pasting formatted text — For best results use plain text. Rich formatting can add unexpected characters.
- Forgetting to copy — The result is not saved. Copy before closing the tab or refreshing.
