The Text Line Wrapper tool breaks long lines of text at a specified character width, ensuring no line exceeds your chosen limit. It intelligently wraps at word boundaries (spaces) whenever possible, so words are not split in the middle. This is essential for formatting commit messages (commonly limited to 72 characters), preparing text for terminals or console output, formatting emails for fixed-width displays, or creating readable plain-text paragraphs. Existing line breaks in your text are preserved, and wrapping is applied within each paragraph. All processing runs client-side in your browser — your text is never uploaded to a server.
About Text Line Wrapper
Text Line Wrapper is a browser-based formatting tool that breaks long lines of text so that no line exceeds a specified number of characters. The tool wraps at spaces whenever possible, meaning words are kept intact and only split if they exceed the maximum line length on their own. Existing line breaks are preserved — wrapping is applied within each paragraph block.
This tool is commonly used for formatting git commit messages (the widely accepted convention is 72 characters per line), preparing text for monospaced terminal output, creating plain-text email bodies, and formatting code comments to stay within column limits.
How to Use Text Line Wrapper
- Set the Max characters per line (default is 72, which is standard for commit messages).
- Paste or type your text into the Text area.
- Click Wrap text to apply the wrapping.
- Review the result and use Copy result to copy the wrapped text to your clipboard.

Technical Details
The wrapping algorithm processes each paragraph (text between existing newlines) independently. For each paragraph, it scans forward from the start of the line to find the last space character that falls within the maximum width. If found, it inserts a line break at that space. If no space is found within the limit (i.e., a single word exceeds the max width), the word is split at the character limit. This greedy word-wrap algorithm runs in O(n) time where n is the text length. All processing happens in JavaScript within your browser with no external dependencies.
