About Remove Line Breaks

Remove Line Breaks is a free online tool that strips unwanted newline characters from any block of text. When you copy content from a PDF, a plain-text email, or a word processor, the line endings that were needed for the original layout often end up embedded in the text itself — breaking what should be a continuous sentence into short, broken fragments. Paste that text here and the tool reassembles it into clean, flowing prose in one step.

The tool offers two modes for different situations. "Replace with Space" is designed for the most common case: PDF extracts and reflowed paragraphs where each line ends with a hard break but the words should stay joined. It replaces every line break with a single space and collapses any resulting double-spaces, so word boundaries are never lost. "Remove Entirely" is for use cases like joining lines of code, combining short data fields, or building a single-line string where no separator is needed at all. Unlike a general-purpose find-and-replace tool, both modes handle all three line-ending formats — Windows (CR+LF), Unix (LF), and legacy Mac (CR) — so you never have to pre-process the line endings first.

All text processing runs entirely inside your browser using JavaScript. Nothing you paste is sent to a server, stored, or logged. The result updates the moment you type or toggle the mode, so there is no submit button to click and no waiting for a round trip. The tool is free to use without an account, with no paste-size limits beyond what your browser can handle.

Key Features

check_circle

Two distinct removal modes

"Replace with Space" preserves word boundaries by substituting each line break with a space and collapsing consecutive spaces. "Remove Entirely" joins every line with no separator, which is useful for code strings or delimited data.

check_circle

Handles all three line-ending formats

Windows CR+LF, Unix LF, and legacy Mac CR line endings are all detected and processed in a single pass, so you never need to convert line endings before using this tool.

check_circle

Live counter showing breaks found

A running count of line breaks in the input appears in the toolbar as you type, so you can confirm the tool is working and see exactly how many breaks were present.

check_circle

Instant output, no submit button

The result updates automatically as you type or switch modes. There is no button to press and no page reload — paste your text and the cleaned version is ready immediately.

check_circle

100% client-side and private

Processing uses only in-browser JavaScript. Your text is never uploaded, transmitted, or stored, making it safe for confidential documents, internal reports, and personal data.

check_circle

One-click copy

Copy the cleaned output to your clipboard with a single button click and paste it directly into your target application without touching the mouse again.

Example

A PDF extract where each line ends with a hard break is reassembled into a single clean paragraph using "Replace with Space" mode.

Common Use Cases

  • arrow_circle_right

    Fixing PDF copy-paste

    PDF files lay out text line by line, so pasting a paragraph into another application produces a hard break at the end of every line. "Replace with Space" mode joins those fragments back into continuous sentences instantly.

  • arrow_circle_right

    Preparing text for APIs and databases

    Many API fields and database columns expect a single-line string with no embedded newlines. Use "Remove Entirely" mode to strip breaks before inserting values into JSON payloads, SQL statements, or spreadsheet cells.

  • arrow_circle_right

    Cleaning up plain-text email threads

    Forwarded plain-text emails often arrive with hard-wrapped lines at 72 or 80 characters. This tool unwraps them so you can quote or rephrase the content without editing line by line.

  • arrow_circle_right

    Joining split song lyrics or poetry for processing

    Lyrics databases and translation tools work better on full lines rather than split verses. Merge stanzas into single continuous strings before feeding them into another tool or exporting them.

  • arrow_circle_right

    Collapsing multi-line CLI output into one line

    When a command outputs several lines you want to combine into a single argument or log entry, paste the output here and remove the breaks before using it elsewhere in a script or document.

Frequently Asked Questions

What is the Remove Line Breaks tool? expand_more
Remove Line Breaks is an online tool that strips unwanted line breaks (newlines) from your text. You can choose to replace them with spaces to maintain word separation, or remove them entirely to join all text together.
Does it handle Windows and Mac line endings? expand_more
Yes. The tool handles all common line ending formats including Windows (\r\n), Unix/Mac (\n), and old Mac (\r) line breaks, detecting and processing all three in a single pass.
Will it remove paragraph breaks too? expand_more
Yes, the tool removes all line breaks including the blank lines that separate paragraphs. If you need to keep paragraph structure intact, process your text in sections or use Find and Replace Text to target only single newlines.
Is my text secure? expand_more
Yes. All processing happens locally in your browser using JavaScript. No data is sent to any server, stored, or logged.
What is the difference between "Replace with Space" and "Remove Entirely"? expand_more
"Replace with Space" substitutes each line break with a single space and then collapses any run of multiple spaces, so words that were split across lines are joined correctly. "Remove Entirely" simply deletes every newline character without inserting anything, which merges adjacent characters directly — useful for code strings or data fields where no separator is wanted.
How is this different from Remove Empty Lines? expand_more
Remove Empty Lines targets only blank lines — lines that contain nothing or only whitespace — and keeps the non-empty lines intact. Remove Line Breaks targets every line break character regardless of whether the line has content, joining all lines together. Use Remove Empty Lines to tidy multi-paragraph text; use this tool when you need to flatten the entire block into one continuous string or paragraph.
Can I use this to fix text copied from a PDF? expand_more
Yes, that is the most common use case. PDF layout engines insert a hard line break at the end of each visual line, so pasted text arrives as short fragments. Select "Replace with Space" mode to rejoin them into full sentences.
Is there a limit on how much text I can paste? expand_more
There is no built-in limit. Because everything runs in your browser, the practical ceiling is your device memory. Very large documents — tens of thousands of lines — process in milliseconds on a modern machine.
