Line Ending Checker
Detect which line ending style your text uses — CRLF (Windows), LF (Unix/Mac), or CR (old Mac) — and see counts of each. Detection only; it does not convert between formats.

Frequently Asked Questions
No — despite older descriptions of this tool suggesting conversion, it only counts and reports which line ending style(s) are present; it doesn't rewrite or export a converted version of your text.
CRLF (\r\n) is the Windows standard, LF (\n) is used by Unix, Linux, and modern macOS, and CR (\r) alone was used by classic (pre-OS X) Mac systems — mixing styles within one file can cause display or diff issues in some editors and version control tools.
It reports whichever style has the highest count when line endings are mixed, using CRLF as the tiebreaker priority if counts are equal.
No — detection happens entirely in your browser.
