About Line Break Remover Online
This tool removes line breaks from text, joining everything onto a single line. You can replace each break with a space (the default), nothing (concatenated), or any custom character. Optionally collapse runs of breaks into a single one if you only want to remove empty lines.
Useful when pasting text that wrapped awkwardly across multiple lines (PDFs are notorious for this), when preparing data for systems that don't accept multi-line input, or when joining a paragraph that should be a single sentence for analysis or comparison.
It also supports the reverse: adding line breaks at sentence boundaries or fixed character widths if you need to re-wrap a paragraph.
How to use this tool
How to flatten text to a single line
Paste multi-line text
Put content with line breaks into the Text field. Both \n and \r\n endings are accepted.
Know what collapses
Every line break becomes a single space; runs of whitespace (tabs, multiple spaces) collapse to one space; leading and trailing whitespace is trimmed.
Run the flatten
Press Run. The output is one continuous line suitable for SMS, single-line form inputs, or a CSV cell.
Copy the result
Copy the flattened text. If you need paragraph markers kept, insert a sentinel (e.g. " — ") with Find/Replace before running.
