Paste your text and get clean, flowing paragraphs or a single line instantly. It handles both Windows and Unix line endings and runs entirely in your browser.













How to Use the Line Break Remover





Paste, pick a mode, copy.





Step 1: Enter or paste your input





Paste your text into the Input text box. Typical sources are PDFs, email threads, scanned documents, subtitles, chat logs and lists from spreadsheets. Clear empties the box.





Step 2: Choose your options





Pick a Mode:





    

  • Replace line breaks with spaces: joins everything into one continuous block, with a space where each break was. Best for single paragraphs.
    • 




  • Keep paragraphs, join lines inside them: keeps blank lines between paragraphs and joins the lines within each paragraph. Best for multi-paragraph PDF text.
    • 




  • Remove line breaks completely: deletes breaks without adding anything, for data like long codes or hashes split across lines.
    • 




  • Replace with custom text: puts your own separator where each break was. The default is ” | “, but you can use a comma, semicolon or anything else in the Custom replacement field.
    • 






Spaces and tabs around each line break are cleaned up automatically, so you do not end up with double spaces.





Step 3: Copy, download or apply the result





The result updates as you type, with the number of line breaks removed and the input and output character counts. Click Copy or Download to save it as a text file.













Why Unwanted Line Breaks Appear





Unwanted line breaks are hard returns inserted at the end of each visual line instead of only at the end of each paragraph. They usually appear when text moves from a fixed layout into a flexible one.





Common causes:





    

  • PDFs. A PDF stores text by position on the page. When you copy it, most viewers add a line break at the end of every printed line, so one paragraph becomes ten short lines.
    • 




  • Plain-text email. Many email systems wrap plain-text messages at around 72 to 80 characters with hard breaks. Replies quoted several times get even shorter lines.
    • 




  • Old documents and scans. OCR text and typewritten documents often have a break at every line.
    • 




  • Terminal and log output. Command output is wrapped to the window width.
    • 




  • Subtitles and captions. Each caption is split into short lines for the screen.
    • 






When this text is pasted into a website, document or form, the breaks stay. It looks ragged on wide screens, breaks into odd pieces on phones, and confuses word counts and readability checks. A line break remover fixes all of it in one step.













Removing Breaks While Keeping Paragraphs





The “Keep paragraphs” mode is the one most people need for PDFs and emails. It works in two steps:





    

  1. It splits the text into paragraphs wherever there is a blank line (two line breaks with only spaces in between).
    2. 




  2. Inside each paragraph, it replaces every line break with a single space.
    3. 






The paragraphs are then joined back together with one blank line between them.





This only works if the original text has blank lines between paragraphs. Many PDFs do, but some do not. If yours comes out as one huge block, the source had no blank lines. In that case, add a blank line by hand before each new paragraph and run it again, or use Find and Replace Text with a regex if paragraphs start with a pattern, like a number or a heading.





Headings and short lines like “Chapter 2” that are followed by a blank line stay on their own. Headings without a blank line after them will be joined to the next sentence, so check those.













CRLF vs LF: Line Endings Explained





Not every line break is the same character:





Line endingCharactersUsed by
LF\n (line feed)Linux, macOS, most web and code tools
CRLF\r\n (carriage return + line feed)Windows, many email standards and some exports
CR\r aloneVery old Mac systems





Text copied from Windows programs or Windows-created files often has CRLF endings. Tools that only look for \n can leave stray \r characters behind, which show up as odd symbols or break scripts.





This line break remover handles both LF and CRLF, so text from Windows, Mac and Linux all comes out clean. Old CR-only files are rare today; if you have one, open it in a modern editor and save it with LF or CRLF endings first.





Developers sometimes need to convert line endings rather than remove them. Code editors like VS Code let you switch between LF and CRLF in the status bar.













Fixing Text Copied From PDFs and Emails





A quick workflow for clean PDF text:





    

  1. Copy the text from the PDF and paste it here.
    2. 




  2. Choose Keep paragraphs, join lines inside them.
    3. 




  3. Check for hyphenated words. PDFs often split words at line ends with a hyphen, like “informa-” and “tion”. These become “informa- tion” after joining. Search for “- ” and fix them, or use Find and Replace with regex (\w)- (\w) and replace with $1$2, checking real hyphenated words afterwards.
    4. 




  4. Run the result through the Extra Spaces Remover to clean double spaces.
    5. 






For emails, remove quote markers like “>” at the start of lines first with Find and Replace, then join the lines.





For lists you want on one line, such as keywords or emails, use custom mode with “, ” as the replacement, or the Comma Separator if you also want quotes, sorting or deduplication.

Common mistakes and quick fixes





    

  • Words glued together. You used Remove completely on normal text. Switch to Replace with spaces.
    • 




  • Everything in one block. The source has no blank lines between paragraphs. Add them, then use Keep paragraphs.
    • 




  • Headings merged into text. Add a blank line after each heading first.
    • 




  • Need lines numbered instead. Use the Line Numbering Tool.

To remove line breaks from text, paste it into a line break remover and choose a mode. Replace line breaks with spaces joins everything into one block, while Keep paragraphs joins lines but keeps the blank lines between paragraphs. Then copy the result. The tool works with both Windows and Unix line endings.









Text from PDFs has line breaks because PDFs store text by its position on the page, not as flowing paragraphs. When you copy it, most PDF viewers add a hard line break at the end of every printed line. Pasting that text elsewhere keeps the breaks, so it looks ragged until you remove them.









CRLF and LF are two ways of marking the end of a line. LF, a single line feed character, is used by Linux, macOS and most web tools. CRLF, a carriage return followed by a line feed, is used by Windows and many email standards. Mixed endings can cause stray characters in some tools.









You get rid of line breaks by replacing them with spaces or removing them. In an online line break remover, paste the text and pick a mode. In Word, use Find and Replace with ^p for paragraph marks. In code editors, use regex find and replace with \n and replace with a space.









To get rid of newline characters, replace each \n, and \r\n on Windows, with a space or nothing. Paste the text into this line break remover and choose Replace line breaks with spaces or Remove line breaks completely. In code, use a replace function, such as text.replace(/\r?\n/g, ‘ ‘) in JavaScript.
