よくある質問

What is CRLF vs LF?
CRLF is two characters: carriage return + line feed (\r\n), common on Windows. LF (\n) is a single newline used on Linux and macOS. Old Mac OS used CR (\r) alone.
Why does Git show \\r\\n warnings?
Mixed line endings cause noisy diffs. Normalize to LF or CRLF for your project (e.g. .gitattributes) and use this tool to fix pasted files or snippets.
Does this tool upload my text?
No. Conversion happens locally in your browser.
