Remove Line Breaks

Remove Line Breaks is a versatile free online tool designed to clean up text by removing unwanted line breaks and newline characters with intelligent formatting options. Whether you're cleaning up copied text from PDFs, preparing content for email systems that don't handle line breaks properly, formatting text for specific platforms, or consolidating multi-line text into a single continuous flow, this tool provides three powerful modes to handle any line break removal scenario. The tool offers complete control over how line breaks are handled: Remove All mode completely eliminates all line breaks to create a single continuous line of text, perfect for removing formatting from copied PDF text or preparing content for systems that don't support line breaks; Replace with Space mode converts each line break into a single space character, maintaining word separation while creating flowing text ideal for email content, form submissions, or text that needs to maintain readability without line breaks; and Keep Paragraphs mode preserves paragraph structure by keeping double line breaks (paragraph separators) intact while removing single line breaks within paragraphs, perfect for cleaning up text where paragraph structure matters but unwanted mid-paragraph breaks need to be removed. All text processing happens entirely client-side in your browser using efficient JavaScript regex patterns, ensuring complete privacy—your text never leaves your device, isn't uploaded to any server, and isn't stored anywhere. Common use cases include cleaning up text copied from PDF documents which often introduces unwanted line breaks mid-sentence, preparing content for email marketing platforms that may not properly handle line breaks, formatting text for CSV files or databases where line breaks cause import issues, consolidating multi-line addresses or contact information into single-line format, removing line breaks from code snippets or logs for better readability in certain contexts, preparing text for SMS or messaging platforms with specific formatting requirements, cleaning up text extracted from images using OCR which often introduces erratic line breaks, and formatting content for posting on platforms that interpret line breaks differently than expected. PDF text extraction is a particularly common scenario where this tool excels—when you copy text from a PDF, each line often becomes a separate line in your clipboard, even mid-sentence. This creates choppy, hard-to-read text when pasted elsewhere. The Remove All or Replace with Space modes instantly transform this fragmented text back into flowing, readable paragraphs. For email content, many email systems and ESPs (Email Service Providers) have specific requirements about line breaks—some strip them, some convert them to breaks, and some display them as-is. Using the Replace with Space mode ensures your email content displays consistently across different email clients and platforms. When working with spreadsheets and CSV imports, line breaks within cell data can cause rows to split incorrectly or import to fail entirely. Removing line breaks ensures data imports cleanly into the expected columns. Address formatting is another common use case—shipping labels, mailing lists, and many database systems require addresses on a single line rather than the traditional multi-line format. The Replace with Space mode converts multi-line addresses to single-line format while maintaining all information. The Keep Paragraphs mode is ideal for cleaning up web content, blog posts, or articles where paragraph structure is important but unnecessary line breaks within paragraphs have been introduced through copying, pasting, or CMS quirks. This mode intelligently preserves paragraph boundaries (identified by double line breaks) while merging lines within each paragraph. The real-time statistics display shows before and after metrics including input lines, output lines, lines removed, and character count, helping you understand exactly what changes are being made to your text. The input and output are displayed in separate text areas, making it easy to compare the original and processed text side-by-side. The Copy Output button instantly copies the processed text to your clipboard for easy pasting into your target application, streamlining your workflow. All three modes use carefully crafted regular expressions to handle line breaks accurately: Remove All uses a simple newline character replacement; Replace with Space substitutes each newline with a space character; and Keep Paragraphs uses a more sophisticated pattern that distinguishes between single newlines (to be replaced with spaces) and multiple consecutive newlines (to be preserved as paragraph breaks). The tool handles all common line break variations including LF (Line Feed, \n, used on Unix/Mac), CRLF (Carriage Return + Line Feed, \r\n, used on Windows), and even CR alone (\r, used on old Mac systems). This cross-platform compatibility ensures the tool works correctly regardless of where your text originated. The responsive design ensures the tool works perfectly on desktop computers, tablets, and mobile phones, with text areas that adapt to your screen size while maintaining comfortable editing dimensions. No character limits, no usage restrictions, and no account required—process text of any length, as many times as needed, completely free. The tool works offline once loaded, making it reliable even without internet connectivity. For developers and technical users, the tool is useful for cleaning up log files, removing line breaks from JSON strings for certain APIs, formatting SQL queries for single-line execution, preparing text for command-line tools that expect single-line input, and cleaning up text output from scripts or programs. Content creators use it for preparing social media posts where platform line break handling is inconsistent, formatting text for advertising platforms with specific requirements, cleaning up transcripts from interviews or podcasts, and preparing content for translation services that may charge differently for line-break-heavy text. The clear visual feedback with before/after statistics helps you verify that the line breaks are being removed according to your needs, and you can easily switch between modes to see which produces the best results for your specific use case. Understanding how different systems handle line breaks is crucial in modern digital workflows—what looks perfect in one application may appear broken in another due to line break interpretation differences. This tool gives you precise control over line break formatting, ensuring your text displays correctly in any target system or platform.
