What does this Remove Line Breaks tool do?

This free online line break remover takes text that is spread across many short lines and joins those lines back together. It's the tool you reach for whenever you've copied text out of a PDF, an email client, a text column on a website, or a spreadsheet cell — and the result is a mess of broken sentences that weren't there in the original.

Hard line wrapping is a display feature, not part of the text. A PDF that shows a sentence across three visual lines is really one continuous string. When you copy that text out, every visual line wrap becomes a real newline character, and the result is a paragraph that's shattered into fragments. This tool puts it back together.

You get full control over how the lines are joined. You can flatten everything into a single line, keep paragraph boundaries intact so the document structure survives, or convert a vertical list into a comma-separated one-liner for import into a database or spreadsheet. Every option runs locally in your browser, so nothing you paste leaves your device.

Modes explained

All into one line

Every line break is removed and replaced with the separator you choose. The output is a single continuous line of text. This is what you want when the source was hard-wrapped and the whole thing is really one paragraph — a product description copied from a PDF, a single-line address, or a long text string destined for a database field.

Keep paragraphs

Single line breaks inside a paragraph are joined, but blank lines (double newlines) are preserved as paragraph boundaries. This is the mode that fixes a document copied from a PDF: the mid-sentence wraps disappear, and the paragraph structure you actually want stays visible. Use it for articles, essays, emails, and any document where paragraph breaks carry meaning.

Replacement options

When two lines are joined, the separator between them matters. These are the choices and when each one is useful:

SeparatorWhat it doesBest for
SpaceJoins lines with a single spaceFixing hard-wrapped paragraphs, prose, articles
NothingConcatenates lines with no gapReassembling text where the wrap didn't add a space (URLs, code, hyphenated words)
CommaJoins lines with , Turning a vertical list into a CSV-ready line
PipeJoins lines with | Building delimited strings for logs or exports
CustomAny text you type, including \n and \tSemicolon lists, tab-separated output, or any unusual delimiter

If you choose "Space" and the option to trim whitespace is on, you'll end up with exactly one space between every joined line, which is usually what people want.

Line endings — CRLF, LF, and CR

Different operating systems mark the end of a line with different invisible characters. Before doing anything else, this tool normalises every line ending to a single \n so mixed input is handled consistently.

FormatCharactersUsed by
Windows (CRLF)\r\n (0x0D 0x0A)Windows, DOS, many Windows text editors
Unix (LF)\n (0x0A)Linux, macOS, BSD, Docker, most modern systems
Mac classic (CR)\r (0x0D)Classic Mac OS (pre-OS X), some legacy files

You'll see mixed endings all the time when files move between systems — a PDF generated on Windows, a log file from a Linux server, a template created on an old Mac. The tool handles all three without you having to think about it.

Common use cases

  • Fixing text copied from PDFs — The single most common reason. A paragraph that came out as nine short lines becomes one clean paragraph in Keep paragraphs mode.
  • Cleaning email replies — Email clients wrap quoted text at odd widths. Join the lines back and the message reads the way it was written.
  • Vertical list to CSV — Copy a list of one item per line and turn it into a comma-separated single line ready for import into a spreadsheet or database.
  • Flattening spreadsheet cells — A cell with line breaks inside it can be flattened to a single string for use in a URL, a search query, or an API call.
  • Preparing text for forms — Many single-line fields (product titles, meta descriptions) reject multi-line input. Flatten the text first.
  • Reassembling addresses — Addresses copied from PDFs often break mid-line. Join them into the canonical single-line format.
  • Building test data — Generate long single-line strings for testing parsers and form validators.

Frequently asked questions

A line break remover takes text that is split across multiple lines and joins those lines back together. It is commonly used to fix text copied from PDFs, emails, and web pages where hard line wrapping has broken sentences into many short lines.
Yes. Choose the 'Keep paragraphs' mode to preserve blank lines between paragraphs while flattening the line breaks inside each paragraph. Single newlines become spaces (or your chosen separator) and double newlines stay as paragraph breaks.
You can replace each line break with a space, nothing (concatenating the text), a comma, a pipe, or a custom separator of your choice. This lets you turn a vertical list into a comma-separated list, join text into a single line, or build any format you need.
Yes. The tool normalises Windows (CRLF), Unix (LF), and classic Mac (CR) line endings first, so mixed input from different systems is handled correctly.
Remove Line Breaks joins lines together. Line Break Converter changes the style of line endings (CRLF to LF or vice versa) without removing them. Use the converter when you need consistent line endings, and this tool when you want to join lines. You can find the converter at /line-break-converter.
No. Everything runs locally in your browser using JavaScript. Your text never leaves your device, there is no server processing, and nothing is logged or stored.
Yes. The tool is fully responsive and works on phones, tablets, laptops, and desktops.
