Online Line Break Conversion Tool Function Introduction

About line breaks

What is a line break?

A line break is a special character used to indicate the end of a line in text files. Different operating systems use different line break standards, which can cause formatting issues when sharing text files between platforms.

When transferring text files between different operating systems (Windows, macOS, Linux), you may encounter the following issues:

  • Unix/Linux files opened in Windows display as a single line
  • Windows files opened in Unix/Linux display extra ^M characters
  • Code files display garbled formatting on different systems
  • Script files cannot be executed properly due to line break issues

Supported Conversion Formats

  • Windows format (CR+LF)
    - Representation: \r\n (carriage return + line feed), used for DOS/Windows text files
  • Unix/Linux format (LF)
    - Representation format: \n (line feed), used in text files on Unix, Linux, and macOS (modern versions)
  • Classic Mac format (CR)
    - Representation format: \r (carriage return), used in traditional Mac OS text files

To use this tool:

  1. Paste the file contents into the input area
