Remove Line Breaks
Paste your multi-line text below and choose a replacement character to merge all lines into a single continuous string. Perfect for cleaning up copied text from PDFs, emails, and documents.
How Remove Line Breaks Works
This free online tool strips all line break characters from your text and replaces them with your chosen separator. It handles both Windows-style line endings (carriage return plus line feed, often written as CRLF) and Unix-style line endings (line feed only, LF). After replacing line breaks, the tool also cleans up any extra whitespace that may result from the replacement, ensuring your output is clean and properly formatted.
Processing Steps
The tool first normalizes all line endings by converting CRLF sequences to LF. Then it replaces each remaining LF character with your chosen separator: a space, nothing (direct concatenation), a comma followed by a space, or a semicolon followed by a space. Finally, it collapses any resulting multiple consecutive spaces into a single space and trims leading and trailing whitespace.
Why You Need to Remove Line Breaks
Line breaks frequently cause problems when copying text between different applications and formats. When you copy text from a PDF document, each visual line in the PDF becomes a separate line in your clipboard, even if the original text was a single flowing paragraph. Email clients often insert hard line breaks at certain column widths. Spreadsheet data exported as text may have unexpected line breaks within cells. Terminal output and log files contain line breaks that make it difficult to paste content into single-line input fields.
Web developers often need to remove line breaks when preparing text for JSON strings, HTML attributes, or database fields that expect single-line input. Content managers copying text from design tools like Figma or Sketch encounter artificial line breaks that break the flow of paragraphs. Researchers copying abstracts from academic databases often get text with line breaks at every visual line boundary. This tool solves all these problems with a single click.
Replacement Options Explained
The space replacement is the most common choice and works perfectly for merging paragraph lines that were broken at visual line boundaries. The empty replacement (nothing) concatenates lines directly, which is useful for combining split URLs, file paths, or base64 strings. The comma replacement is ideal for converting a list of items on separate lines into a comma-separated list. The semicolon replacement serves a similar purpose for data that uses semicolons as delimiters, common in European CSV formats and some database exports.
Common Use Cases
Students cleaning up text copied from PDF textbooks and research papers. Marketers preparing email content that was drafted in a text editor. Programmers converting multi-line strings into single-line format for configuration files. Data entry professionals cleaning up addresses and descriptions copied from various sources. Writers merging text that was manually line-wrapped in a plain text editor.
