About Line Break Remover / Adder
A line break tool is a text formatting utility that allows users to add or remove line breaks from any text input. This tool helps convert between single-line and multi-line formats, making it essential for preparing text for different platforms, applications, or formatting requirements.
Why use a Line Break Remover / Adder?
Using a line break tool saves time when reformatting text for different contexts such as converting paragraphs to single lines for databases, or adding breaks for better readability. It eliminates manual editing errors and ensures consistent formatting across different platforms and applications.
Who is it for?
This tool is perfect for content managers preparing text for different CMS platforms, developers formatting code comments and strings, social media managers adapting content for various platforms, data entry specialists working with CSV files, and writers who need to reformat text for different publication requirements.
How to use the tool
Paste your text into the input field
Choose whether to add or remove line breaks
When removing, pick what replaces each line break (space, nothing, comma, pipe, or dash); when adding, set the line width (10-200 characters)
The output updates automatically; there is no process button
Copy the formatted text for use in your target application
Frequently Asked Questions
How do I add or remove line breaks?
Paste text into the input. Choose a mode. Remove replaces every line break with a space, nothing, a comma, a pipe, or a dash. Add wraps the text at a chosen width (10-200 characters, default 80), keeping blank-line paragraph breaks. Output appears live. Runs entirely in your browser — your text never leaves the device. Useful for: pasting text copied from PDFs (which adds line breaks mid-sentence), preparing text for CSV/JSON, joining wrapped lines.
What's the difference between CRLF, LF, and CR line endings?
Three conventions for marking line breaks. CRLF (`\r\n`): Windows. LF (`\n`): Unix, Linux, macOS (since OS X). CR (`\r`): classic Mac OS (pre-OS X), now obsolete. Most modern systems and tools handle both CRLF and LF transparently, but some legacy applications care. Git can automatically normalize on commit (`core.autocrlf` setting). For consistency, choose one style across your codebase — typically LF (Unix-style) unless Windows compatibility is a hard requirement.
Is my text sent to a server?
No — line break manipulation runs entirely in your browser via JavaScript string methods. Your text never reaches a server, never gets logged. Verify in DevTools' Network tab: zero HTTP requests during processing. Safe for sensitive drafts. The operations are deterministic string transformations — no server processing needed.
How do I remove line breaks from PDF-copied text?
PDFs often include 'soft' line breaks at the end of each visual line, which interrupt sentences when you paste into a text field. Use Remove mode with 'Space' as the replacement to join the lines into one flowing paragraph. Note that every line break is replaced, including blank lines between paragraphs, so separate paragraphs are joined too. Headers, bullet points, and lists that legitimately need line breaks will be merged as well, so review the output.
Can I split text into lines by sentence or word?
No. Add mode wraps text at a maximum line width (10-200 characters), breaking between words and keeping blank-line paragraph breaks. It does not split by sentence or put each word on its own line. For more complex splitting, use a regex tool or a programming language.
Does this convert between Unix (LF) and Windows (CRLF) line endings?
Not as a selectable option. The tool reads CRLF, LF, and CR line endings as line breaks and its output uses LF (`\n`). So pasting Windows text and copying the result gives you LF line endings, but you can't choose CRLF or CR. For files, command-line tools work: `dos2unix file.txt` converts CRLF to LF; `unix2dos file.txt` does the reverse. For Git repositories, set `core.autocrlf` in your `.gitconfig`. Most code editors have a line-ending switcher in the status bar.
What's a 'blank line' and how do I handle them?
A blank line is a line containing only whitespace (or no characters at all). Two consecutive line breaks (`\n\n`) create a blank line between paragraphs. This tool has no separate 'remove blank lines' option: Remove mode replaces every line break (so blank lines disappear along with the paragraph structure), and Add mode preserves blank-line paragraph breaks. For Markdown, blank lines separate paragraphs, so use Add mode if you need to keep them. To delete empty lines from a list, use the [Remove Duplicate Lines](/tools/remove-duplicate-lines/) tool with its empty-line option.
Does this handle multi-byte characters and Unicode?
Yes — multi-byte characters (CJK ideographs, emoji) are unaffected by line break manipulation. The tool only recognises CRLF, LF, and CR as line breaks; other Unicode separators (U+2028, U+2029) are not treated as line breaks. For text content with embedded HTML or markup, the operations don't interpret the markup — they just process the literal characters.
