Remove Line Breaks

It strips newline characters - both Unix line feed and Windows carriage return plus line feed - and collapses the resulting text into one continuous block. You can choose to replace each break with a single space so words do not run together, or remove them outright for slug-like

What does this tool remove from my text?
It strips newline characters - both Unix line feed and Windows carriage return plus line feed - and collapses the resulting text into one continuous block. You can choose to replace each break with a single space so words do not run together, or remove them outright for slug-like output. Tab characters and trailing whitespace at the end of each line are also normalized at the same time.
When would I need to remove line breaks?
Pasting text from PDFs, emails, or terminal output often introduces hard breaks at every visual line, which breaks reflow when you paste into Word, a CMS, or a chat. Cleaning the breaks turns the text back into proper paragraphs that wrap naturally to the container width. It is also useful when preparing single-line CSV cells or JSON string values where embedded newlines would corrupt the format.
Will it preserve paragraph breaks?
Yes - the tool offers an option to keep blank lines between paragraphs while removing only the breaks inside each paragraph. Internally it looks for two or more consecutive newlines and treats them as a paragraph separator. If you choose the strict mode, every newline is removed and you get one long line, which is what you want for URL parameters or SQL queries that span multiple lines.
How does it handle different operating system line endings?
Windows uses CRLF, classic Mac used CR, and Linux and modern macOS use LF. The tool normalizes all three so the result is consistent regardless of where the text came from. This matters when text passes between systems - for example, a CSV created on Windows opened on Linux often shows extra blank rows because tools see the trailing CR as a separate line.
Does removing line breaks affect formatting like markdown or code?
Yes, with caveats. Markdown uses line breaks to separate list items, headings, and code blocks, so flattening the text destroys structure. Source code typically requires line breaks to remain valid in languages like Python where indentation is significant. Use the tool only on prose, single-line URLs, or text destined for fields that re-wrap automatically.
Can I use this to clean text copied from a PDF?
Absolutely - that is one of the most common use cases. PDFs export each visual line with a hard break, which makes the text unusable for further editing. Run it through this tool with the option to keep paragraph breaks enabled, and you get clean prose ready to paste into Word, Notion, or your favorite editor without manually deleting hundreds of stray newlines.
