Why this tool is useful
Use line-ending normalization before committing generated files, comparing fixtures or passing text between Windows and Unix-oriented tools.

Line Ending Converter
Normalize mixed CRLF, LF and CR line endings to one selected convention and report the original newline inventory.
Ready. Your working data stays in this browser.
How it works
The page counts CRLF pairs before lone CR and LF characters, replaces every recognized newline with an internal separator and emits the requested sequence.
Practical example
A document containing both Windows and Unix newlines can be exported as consistent LF without changing any visible line content.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
