What Are Line Breaks?
Line breaks (also called newlines) are invisible characters that end a line of text and start a new one. Adding them strategically improves readability, creates visual separation, and helps organize information into scannable formats.
Breaking Modes Explained
Sentences: Adds a line break after each sentence (periods, exclamation marks, question marks). Perfect for improving paragraph readability.
Commas: Adds a line break after each comma. Ideal for converting comma-separated lists into vertical lists.
Spaces: Adds a line break after each space. Useful for putting each word on its own line.
Custom: Adds a line break after your specified character or string (;, |, ::, etc.). Maximum flexibility for any separator.

Frequently Asked Questions
How does the tool add line breaks?
The tool searches for your chosen separator (sentences, commas, spaces, or custom) and replaces it with a line break character (\n). It also cleans up extra whitespace and leading/trailing line breaks.
Does it work offline?
Yes! All processing happens locally in your browser. After the initial page load, you can add line breaks completely offline. Your text never leaves your device.
Is my text data private?
Absolutely. All processing happens in your browser (client-side). Your text never leaves your device, and we never log, track, or collect any data. Works completely offline.
Can I use multiple separators at once?
Not simultaneously. Choose one breaking mode at a time. For complex formatting needs, process the text multiple times or use Custom mode with the most common separator.
What happens to the original separator?
- Sentences: Punctuation is preserved (
.,!,?) - Commas: Commas are preserved
- Spaces: Spaces are removed (replaced with line breaks)
- Custom: Your separator is preserved
Can I undo the changes?
The text is replaced in the editor. To keep both versions, copy your original text before processing or download it first.
What file formats can I upload?
Any text-based file format (.txt, .md, .csv, .log, .html, etc.). Binary files are not supported.
How do I use Custom mode?
Select “Custom” radio button, enter your separator in the text field (e.g., ;, |, --), then click “Add Line Breaks”. The tool will break at each occurrence of your separator.
