How to Remove Line Breaks Online

About the Remove Line Breaks Tool

The Remove Line Breaks tool strips all newline characters (\n, \r\n, \r) from your text, joining everything into a single continuous string. This is one of the most practical text-processing utilities for developers, content editors, and data analysts.

Why You Need This Tool

Copy-Paste Formatting Issues

When you copy text from PDFs, emails, or web pages, it often comes with unwanted line breaks that break your workflow. Our tool cleans it up instantly.

Data Preparation for APIs

Many APIs and database inserts expect single-line strings. Multi-line text can cause JSON parsing errors, SQL injection vulnerabilities, or failed API calls.

Code String Literals

When embedding multi-line text as a JavaScript or Python string, you often need to first collapse it to one line and then add your own escape characters.

Modes Available

• Remove All Line Breaks — Joins everything into one line
• Remove Extra Line Breaks — Keeps single line breaks, removes double/triple spacing
• Replace with Space — Replaces each line break with a space so words don't run together

Common Use Cases

| Scenario | Problem | Solution | |----------|---------|----------| | PDF text extraction | PDFs add breaks at page width | Remove all breaks | | Email template text | Outlook adds CRLF breaks | Remove \r\n | | CSV data prep | Multi-line cells break CSV parsing | Collapse to single line | | JSON string value | Newlines break JSON | Escape or remove breaks | | SQL query building | Multi-line strings can fail | Single-line input |

Technical Details

Line break characters differ by operating system:

• Windows: \r\n (CRLF — Carriage Return + Line Feed)
• Unix/Linux/Mac: \n (LF — Line Feed only)
• Old Mac (pre-OS X): \r (CR — Carriage Return only)

Our tool handles all three formats automatically.
