Remove Line Breaks Tool
Remove Line Breaks Tool flatten multiline text join copied lines replace newline charactersTurn pasted lines into continuous text
Paste text, choose what should sit between former lines, and select Remove line breaks. Space mode is safest for prose. Nothing joins characters directly, while a custom separator works well for short lists.
What the tool changes
The browser recognizes Windows CRLF, older CR, and Unix or modern macOS LF endings. All three become the selected separator. In space mode, leading and trailing whitespace on each line is removed and blank lines are skipped, preventing a pasted paragraph from gaining clusters of spaces. Other visible characters remain untouched.
Choose the separator for the job
Use one space when email, PDF, or narrow-column text wraps into unwanted lines. Use nothing only when breaks split a code, identifier, or word and no separator belongs there. A custom value such as a comma followed by a space can turn a simple vertical list into an inline list. The custom separator is literal; typing a backslash and n does not create another line break.
Worked example
Start with three lines containing “red”, “green”, and “blue”. Space mode returns “red green blue”. Nothing returns “redgreenblue”. A custom separator of “ | ” returns “red | green | blue”. Blank lines between the colors are ignored in space mode but remain meaningful separator positions in custom mode.
Check meaning after flattening
Line breaks can carry structure. Addresses, poems, source code, Markdown, tables, and numbered instructions may become misleading when flattened. Read the result before pasting it elsewhere. If copied PDF text breaks only because of visual wrapping, spaces usually restore readable sentences; if it uses hard paragraph breaks, manual paragraph editing may still be needed.
Limitations and privacy
Text stays in this browser and is not uploaded. The tool does not parse HTML, preserve paragraphs, repair end-of-line hyphenation, detect columns, understand list punctuation, or decide which breaks were intentional. It works on pasted plain text, not uploaded documents. Browser memory limits the practical size of an input.
Remove Line Breaks FAQ
Will spaces inside a line change?
No. Only whitespace touching line boundaries is normalized in space mode.
Why did two words join?
Nothing mode removes the boundary entirely; switch to one space for ordinary prose.
Can I insert commas?
Yes. Choose custom separator and enter a comma, with a following space if wanted.
