Paste your text, then press 'Remove Line Breaks' under Whitespace & Line Cleaners. Every line break becomes a single space, so the text turns into one continuous line. It handles Windows, Mac and Linux line endings, and it will not touch spaces elsewhere in your text. If you change your mind, press Undo.

Use 'Join Lines, Keep Paragraphs'. It joins the lines inside each paragraph with a space but keeps one blank line between paragraphs. This is the fix for text copied from a PDF or an email, where every line ends with an unwanted break but the paragraphs should stay separate.

Removing line breaks joins all the lines into one. Removing blank lines keeps your lines separate and only deletes the empty ones between them. Use 'Remove Blank Lines' to tidy a list, and 'Remove Line Breaks' to turn several lines into one.
