What this tool does
This line ending converter standardizes invisible newline characters so files behave consistently across operating systems, editors, Git, and scripts.
Classify CRLF, LF, and CR endings, split text into logical lines, rejoin with the selected target ending, and report distribution.
For most cross-platform web and code projects, LF is a safe default. Use CRLF only when your workflow requires Windows endings.
Example
Sample input is included in the text box. Run the tool to see the processed output and the before/after statistics.
Use cases
- Clean pasted code before review.
- Normalize formatting before committing files.
- Prepare text for editors, terminals, documentation, or data exchange.
- Compare before and after structure using the result metrics.
Tips for better output
- Normalize line endings before file comparison.
- Use LF for Docker and Unix scripts.
- Use .gitattributes to enforce repository line endings.
Processing details
The tool runs in the browser and focuses on safe whitespace, indentation, wrapping, line ending, or column formatting depending on the selected tool.
For critical code or regulated data, validate the final output with your project-specific parser, compiler, linter, or test suite.
FAQ
How do I fix mixed line endings online?
Paste the file content, choose a target ending such as LF or CRLF, and run the converter to normalize every line.
Which line ending should I use for a project?
Use LF for most cross-platform and Unix-based projects, CRLF for Windows-only workflows, and CR only for legacy Classic Mac files.
Why do line endings matter in code files?
Different endings can create noisy diffs, script errors, parsing issues, and inconsistent editor display.
How do I detect CRLF and LF in pasted text?
The tool counts CRLF, LF, and CR patterns and reports whether the input is consistent or mixed.
Can this normalize an entire file?
Yes. Upload or paste the full file content, convert it, then download the normalized result.
