Last updated: July 2026
Copied text often carries line breaks that do not belong. A PDF wraps every line at a fixed width. An email client adds a break after every sentence. Old code comments split across dozens of short lines. This free tool strips those breaks out, or swaps them for something more useful, in one click.
Why Text Ends Up With Too Many Line Breaks
PDFs are built to fit text onto a fixed page width. When you copy from one, every line break from the layout gets copied along with the words. This leaves short, choppy lines instead of full sentences.
Email clients and old software often add a break after every sentence rather than letting text wrap naturally. Word processors do something similar. None of these breaks are meant to stay once the text moves somewhere else.
The Five Types of Line Breaks This Tool Detects
Not every line break is saved the same way. Different operating systems and file formats use different characters. You do not need to know which one your text has. The tool checks for all five and handles whichever ones are present.
| Type | Character | Common Source |
|---|---|---|
| LF | \n | Unix and Mac systems |
| CRLF | \r\n | Windows documents and emails |
| CR | \r | Classic Mac systems and old files |
| Line separator | U+2028 | Text extracted from Word documents |
| Paragraph separator | U+2029 | Text extracted from PDFs |
Three Ways to Handle Line Breaks
A single fix does not work for every case. This tool gives you three modes, so the output matches what you actually need.
When Custom Replacement Comes In Handy
Custom mode solves a different problem than the other two. It turns line-broken data into a format ready for somewhere else.
A list of names copied one per line can be turned into a comma separated list ready for a spreadsheet. A block of address lines can be turned into a single line separated by pipes for a database import. Old text with manual line breaks can be turned into HTML with break tags in place, ready to paste into a web page.
