Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To normalize line breaks, paste your text into the tool and choose the output style: LF (Unix-style, used by macOS and Linux) or CRLF (Windows-style). The normalizer scans for all line-ending types and rewrites them to your chosen single, consistent style.
Normalization runs locally in your browser, so your text is never uploaded. The content of each line stays exactly the same — only the invisible line-ending characters change — so you can copy or download a clean, consistent result safe to use across platforms and tools.
Different systems use different invisible characters to mark the end of a line: Windows typically uses CRLF, while macOS and Linux use LF. When text moves between platforms or is pasted from various sources, the endings can get mixed, which causes broken formatting, noisy diffs, or scripts that misbehave.
Normalizing to a single line-ending style fixes these problems without touching the actual content. This is especially useful for code, config files, CSV data, and any text handed off between Windows and Unix-based systems, where consistent endings keep tools and version control clean.
Short answers for the questions people usually have before trying a utility like this.
Yes. This line break normalizer is completely free to use with no signup or account required.
No. Normalization runs entirely in your browser on your own device, so your text is never uploaded to a server and stays private.
No. It only normalizes the line-ending style. The words and characters of each line stay exactly the same.
Yes. You can convert your text to either LF (Unix-style) or CRLF (Windows-style) output.
Mixed line endings cause broken formatting, noisy diffs, and script errors when text moves between Windows and Unix systems. Normalizing keeps everything consistent.
