Join lines back into paragraphs, replacing each line break with a space or another separator you choose. Useful for un-wrapping text that was hard-wrapped by a PDF or email client, turning a line-per-item list into a single comma-separated line, or prepping text for a field that doesn't accept line breaks at all.

How do you use the remove line breaks tool?
1. Add your text. Paste it directly, upload a file, or drop a TXT/CSV/JSON file onto the input box.
2. Choose a separator and paragraph handling. Pick what replaces each line break, and whether to keep the blank lines between paragraphs.
3. Copy or download the result. Your joined text is ready instantly, with nothing ever sent to a server.
Want to strip whitespace down entirely rather than join lines with a separator? Try Remove All Whitespace. For blank lines specifically, see Remove Blank Lines.
Frequently Asked Questions
How is this different from Remove All Whitespace?
Remove All Whitespace deletes line breaks (and every other whitespace character) with nothing in their place, which merges adjacent words together - "Hello\nworld" becomes "Helloworld". Remove Line Breaks replaces each line break with a space (or another separator you choose) by default, specifically so words don't get mashed together. It's built for un-wrapping readable text back into paragraphs, not for stripping whitespace down to nothing.
What does "keep paragraph breaks" do, and why is it on by default?
Text copied from a PDF or email is often "hard-wrapped" - every visual line has a real line break in it, even though the line is really part of one continuous paragraph, with an actual paragraph break (a blank line) only between paragraphs. With "keep paragraph breaks" on, this tool only joins the line breaks *within* each paragraph and leaves the blank lines between paragraphs alone, so you get clean, readable paragraphs back instead of one giant run-on block of text. Turn it off if you want every single line break replaced, with no distinction between paragraphs.
What are the replacement options for?
By default line breaks are replaced with a space, which is right for turning wrapped text back into normal sentences. Choosing "Nothing" joins lines with no separator at all - use this only when you know word boundaries don't matter. Comma or semicolon are useful for a different job entirely: turning a line-per-item list into a single comma- or semicolon-separated line, like prepping values for a spreadsheet formula or a CSV-style string.
Is this reversible?
No - once line breaks are replaced, the original line structure can't be reconstructed from the output alone. Keep a copy of your original text if you might need the line breaks back.
