How to Convert Line Endings

Input: Windows Format (CRLF)

First line\r\n
Second line\r\n
Third line\r\n

Windows text files use CRLF (Carriage Return + Line Feed) for line breaks, which can cause issues on Unix-based systems.

Output: Unix Format (LF)

First line\n
Second line\n
Third line\n

Unix/Linux text files use LF (Line Feed) only, making them compatible with most development tools and servers.

Line Ending Formats

🐧 Unix/Linux (LF)

Format: \n (Line Feed)

Hex: 0x0A

Used by Linux, macOS, and most modern systems

🪟 Windows (CRLF)

Format: \r\n (Carriage Return + Line Feed)

Hex: 0x0D 0x0A

Used by Windows and DOS systems

🍎 Classic Mac (CR)

Format: \r (Carriage Return)

Hex: 0x0D

Used by classic Mac OS (pre-OS X)
