Line Break Remover
Removes all line breaks, creating one continuous line of text.
About Line Break Removal
The Line Break Remover helps you clean up text by removing unwanted line breaks and newlines. This is useful when copying text from PDFs, emails, or other sources that add unnecessary line breaks.
Processing Modes:
- Remove All: Removes all line breaks, creating one continuous line of text
- Replace with Space: Replaces line breaks with spaces, maintaining word separation
- Keep Paragraphs: Preserves paragraph breaks (double newlines) while removing single line breaks
Common Uses:
- Clean up text copied from PDF files
- Format email content for different platforms
- Prepare text for single-line input fields
- Remove unwanted line breaks from code or data
- Fix text formatting issues
- Prepare content for social media posts
Tips:
- Use "Remove All" for converting multi-line to single-line text
- Use "Replace with Space" to maintain readability when joining lines
- Use "Keep Paragraphs" when you want to preserve document structure
- The tool handles both Windows (CRLF) and Unix (LF) line endings
How It Works
Line breaks (newlines) are control characters that signal the end of a line of text and the beginning of a new one. There are several newline conventions: LF (Line Feed, \n, used in Unix/Linux/Mac), CR+LF (Carriage Return + Line Feed, \r\n, used in Windows), and CR (Carriage Return alone, \r, used in older Mac systems). Text from different sources may use different conventions.
This tool removes or replaces these newline characters using JavaScript string methods. The replace() method with a regular expression pattern matches all newline sequences (handling all conventions) and replaces them with either nothing (to join text), a space (to separate former lines), or a custom character of your choice.
The distinction between "remove" and "replace with space" is important: removing newlines directly concatenates lines without any separator (useful for code or structured data), while replacing with spaces adds a separator between former lines (better for natural language text where sentences were split across lines).

Use Cases
1. Cleaning Copied Text from PDFs
Text copied from PDF documents often contains line breaks at every line of the original document layout, making it unreadable when pasted elsewhere. PDFs typically break lines based on page layout, not sentence structure. Removing these formatting breaks creates flowing text suitable for pasting into documents, emails, or databases.
2. Preparing Text for Single-Line Fields
Many database fields, form inputs, and configuration parameters expect single-line values. Multiline text copied from notes, emails, or documents needs line breaks removed before it can be stored in these fields. Address fields, product descriptions, and metadata fields commonly have this requirement.
3. Code and Query Formatting
SQL queries formatted across multiple lines for readability need to be collapsed to a single line for use in certain tools, log analysis, or embedding in code. Similarly, API payloads that were formatted across multiple lines for debugging need to be collapsed for transmission.
4. Social Media Post Preparation
Text prepared in a word processor often has intentional line breaks that translate differently on social platforms. Some platforms (particularly Twitter/X and LinkedIn) handle line breaks inconsistently. Removing or standardizing line breaks before posting ensures consistent display.
5. Data Import Preparation
Importing data from text files into databases, spreadsheets, or APIs often requires values on single lines. Multi-line text values in imports can break CSV parsing, cause premature row termination, or fail validation. Normalizing text to single lines before import prevents these issues.

Tips & Best Practices
• Replace with space for readable text: For natural language text (articles, emails, paragraphs), replace line breaks with spaces rather than removing them entirely. Direct removal runs words together without separation.
• Preserve paragraph breaks: If you want to keep paragraph separation but remove within-paragraph line breaks, use a two-step approach: first replace double newlines with a placeholder, remove single newlines, then restore double newlines from the placeholder.
• Mind the Windows vs Unix difference: Windows uses \r\n (two characters) while Unix uses \n (one character). The remover handles both, but if you're processing the result programmatically, ensure your target system understands the remaining format.
• Check for trailing spaces: When replacing line breaks with spaces, you may end up with double spaces where lines ended with a space before the break. Consider running the result through a whitespace normalizer.
