About Remove Line Breaks
Remove Line Breaks cleans up text that arrived with awkward newlines — a PDF copy, a wrapped email, a code comment, or a column pasted out of a spreadsheet. Choose Remove all to collapse every line into one continuous run, Keep paragraphs to delete only the single breaks inside a paragraph while leaving the blank-line gaps between paragraphs intact, or Replace with… to swap each newline for a space, comma, semicolon, or a custom separator you type. Windows CRLF and old-Mac CR endings are normalized automatically, and optional toggles collapse repeated spaces and trim each line so the result reads cleanly. It is handy for writers, developers, and data folks who reflow text constantly. Everything runs locally in your browser, so the text you paste never leaves your device.

Common errors & troubleshooting
- Paragraphs merged into one giant block instead of staying separate. — Switch from Remove all to Keep paragraphs. Remove all deletes every break; Keep paragraphs only removes the single breaks inside a paragraph.
- The joined text has double spaces where lines met. — Turn on Collapse spaces to squeeze runs of spaces and tabs down to one, and enable Trim each line to drop stray spaces at line ends.
- Line breaks seem to remain even after joining. — The text likely used Windows CRLF endings — those are normalized automatically, so re-paste the text and confirm you are not looking at soft-wrapped display lines that have no real newline.
- Words ran together with no gap when replacing newlines. — You chose the Nothing separator or left the custom field empty. Pick Space or Comma + space, or type a separator that includes a trailing space.
Frequently asked questions
- How do I keep the gaps between paragraphs but remove the breaks inside them?
- Choose the Keep paragraphs mode. It reflows the wrapped lines within each paragraph into one line while leaving the blank line that separates one paragraph from the next untouched.
- Can I replace line breaks with a comma or another character?
- Yes. Pick the Replace with… mode and select Comma, Comma + space, Semicolon, Space, or Nothing — or choose Custom and type any separator, such as ' | ' or a tab.
- Does this handle Windows CRLF and old-Mac carriage returns?
- It does. CRLF (\r\n) and lone CR (\r) endings are normalized before processing, so text copied from Windows, macOS, or Unix sources all behaves the same way.
- Why does my output still have extra spaces after removing breaks?
- When two lines join, trailing and leading spaces can sit next to each other. Enable Collapse spaces to merge those into a single space and Trim each line to remove edge whitespace first.
- Is the text I paste sent to a server?
- No. Remove Line Breaks runs entirely in your browser using plain JavaScript. The text you paste is processed on your device and is never uploaded to ArrayKit.
