Remove Line Breaks Online

Quickly clean up text by removing or replacing line breaks, paragraph breaks and extra whitespace. This is perfect for fixing copy-pasted content from PDFs, emails or chat exports where breaks were added at every line — leaving you with text that flows like a normal paragraph again. You can also collapse multiple spaces and choose to keep paragraph spacing intact.

When Do You Need to Remove Line Breaks?

Line breaks sneak into text from many sources and break the flow when you paste content into another tool or platform:

  • PDF copy-paste: PDFs often insert a hard line break at the end of every printed line, turning paragraphs into dozens of short fragments.
  • Email bodies: older email clients wrap lines at 76 or 80 characters, inserting breaks mid-sentence.
  • Chat exports (WhatsApp, Slack, Teams): message logs include timestamps and username prefixes on every line.
  • CSV or data files: multi-line field values need to be collapsed to a single line for certain data pipelines.
  • Code editors: copying a variable list or query result with newlines that you need as a comma-separated string.
