LF (\n) is standard for Unix/Linux/macOS, CRLF (\r\n) is the Windows standard, and CR (\r) is the legacy format for older Mac systems. ### Can I remove empty lines while normalizing? Yes, enable the 'Remove Empty Lines' option to automatically strip lines that contain only whitespace or are completely empty. ### Does this tool modify the original file? No, this is a web-based utility. It processes the text you provide in the browser and does not save or modify files on your local machine. ### What does 'Trim Trailing Spaces' do? It removes any spaces or tabs found at the end of each line, which helps in cleaning up messy code or text blocks. ### Is there a limit to the amount of text I can process? The tool can handle large blocks of text, though performance may vary depending on your browser's memory capacity. ## Related tools - [Multiline Merger](https://elysiatools.com/en/tools/multiline-merger): Merge multiple lines into a single line with customizable separators and formatting options - [Prefix Remover](https://elysiatools.com/en/tools/prefix-remover): Remove common prefixes from each line with intelligent detection and customizable options - [Suffix Remover](https://elysiatools.com/en/tools/suffix-remover): Remove common suffixes from each line with intelligent detection and customizable options - [Line Number Remover](https://elysiatools.com/en/tools/line-number-remover): Remove line numbers from text or code with intelligent pattern recognition - [Text Unindenter](https://elysiatools.com/en/tools/text-unindenter): Quickly delete indentation from each text line - [BOM Character Remover](https://elysiatools.com/en/tools/data-bom-remover): Remove BOM (Byte Order Mark) characters from text and file content.
