Remove Line Breaks

Convert multi-line text to single line instantly. Choose custom separators, process multiple files at once, and download with custom filenames.

What is Remove Line Breaks?

Remove Line Breaks is a text formatting tool that converts multi-line text into a single continuous line. It's designed to solve a common problem: when you copy text from PDFs, websites, or documents, unwanted line breaks often appear that break up your text.

This tool gives you complete control over how lines are joined. Choose to replace line breaks with spaces, commas, semicolons, or any custom character. Additional options let you trim extra whitespace and skip empty lines for cleaner results.

Your Files Stay Private: All file processing happens entirely in your browser. Files never leave your device, no server processing occurs, and we don't collect any usage data or file contents. You can safely process sensitive documents knowing that your data remains completely private.

Frequently Asked Questions

How do I remove line breaks and replace them with spaces?

Paste your text into the input area and make sure "Space" is selected as the join option (this is the default). All line breaks will be replaced with single spaces. Enable "Trim Lines" if you also want to remove extra whitespace from each line.

Can I join lines without any separator?

Yes. Select "Nothing" as the join option. Lines will be joined directly with no character between them. This is useful when line breaks have split words or when you're combining code strings.

What file types can I upload for batch processing?

The tool accepts common text-based formats: .txt, .csv, .md, .log, .json, .xml, .html, .css, and .js files. Binary files like images or PDFs are not supported.

How does the filename suffix work?

The suffix is added to each downloaded file's name, just before the extension. For example, with the default suffix "-cleaned", a file named "data.txt" becomes "data-cleaned.txt". You can change the suffix to anything you prefer, or leave it empty to keep the original filename.

Are my files uploaded to a server?

No. All processing happens entirely in your browser using JavaScript. Your files never leave your device and no data is sent to any server. This means you can safely process sensitive or confidential documents.

Why are there extra spaces in my output?

This usually happens when your original text has spaces at the end of lines, or when there are empty lines. Enable both "Trim Lines" and "Remove Empty" options to get clean output without extra separators.

Pro Tip: For the cleanest results, always enable both cleanup options when processing copied text from PDFs or websites.

Can I use a multi-character separator?

Yes. Select "Custom" and enter any string you want, such as " | " (pipe with spaces), " - ", or even longer text. The tool will use your exact input as the separator between lines.

Do my settings get saved?

Yes. Your separator choice and option settings are saved in your browser's local storage. When you return to the tool, your preferences are automatically restored, making repeated tasks faster and more convenient.
