Line Ending Converter

Convert the line endings of any text between the three conventions in use today — LF, CRLF, and CR — while leaving every line's content untouched.

The three conventions:

• LF (\n) — Unix, Linux, modern macOS, and the web's default. The modern common ground.
• CRLF (\r\n) — Windows and classic network protocols (HTTP, SMTP, etc.).
• CR (\r) — classic (pre-OS X) Mac OS. Rare today, but still appears in legacy data and certain hardware logs.

How it works:

• The tool first detects whatever mix of endings your input already has (including a mix of all three in one file, common after pasting from different sources).
• It splits the text into logical lines, then rejoins them using your chosen ending.
• The final line is given an ending too, so the whole block is uniform end-to-end.

Good to know:

• This normalizes mixed endings — if a file has both \n and \r\n lines (a frequent source of Git "mixed line endings" warnings), converting it to one ending fixes that in one step.
• Line content (trailing spaces, tabs) is preserved; only the line terminator changes.
• The metadata reports the original ending breakdown (how many CRLF / LF / CR), so you can see exactly what you started with.
