Line Break Converter

Convert between CRLF, LF, and CR line endings with extra text utilities.

Why Use a Line Break Converter?

Line ending differences are a common source of issues when sharing files between Windows, macOS, and Linux systems. Windows uses CRLF (\r\n), while Unix-based systems use LF (\n). This tool lets you convert between all line ending formats, remove blank lines, sort lines, add line numbers, and trim whitespace — all instantly in your browser with zero data transmission.
