How to use this text tool

  • Paste text copied from a Windows-style file.
  • Run the converter to normalize line endings to LF.
  • Check the CRLF count and mixed-ending warning.
  • Download or copy the LF-normalized output.

What this tool does

This converter changes only line ending characters, turning CRLF sequences into LF while leaving the visible text content unchanged.

Count CRLF, LF, and CR endings, normalize all endings to LF, optionally handle final newline behavior, then report consistency.

Some Windows-only tools may prefer CRLF, but LF is common for Git repositories and Unix-based environments.

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

  • Use LF for many Git, Docker, and Linux workflows.
  • Normalize line endings before comparing files.
  • Keep repository .gitattributes consistent.

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

What is the difference between CRLF and LF?

CRLF uses carriage return plus line feed, common on Windows. LF uses only line feed, common on Unix, Linux, and macOS.

Why does Git prefer LF line endings?

LF avoids noisy diffs in cross-platform repositories and is commonly expected by Unix-based tools.

Will converting CRLF to LF change file contents?

It changes only the invisible line ending characters, not the visible text content.

Can mixed line endings cause issues?

Yes. Mixed endings can create confusing diffs, script errors, or inconsistent editor behavior.

Is LF required on Linux scripts?

Many Linux scripts work best with LF because CRLF can cause interpreter or shell parsing problems.
