How to Use Remove Line Breaks
Basic Text Processing
Converting multi-line text to single line takes just a few steps:
Paste Your Text
Paste your text into the input area on the left. You can also type directly or use the Paste button for quick insertion.
Choose a Separator
Select from the options bar:
- Space - Lines joined with a single space (most common)
- Nothing - Lines joined directly with no separator
- Comma - Lines joined with comma and space
- Semicolon - Lines joined with semicolon and space
- Custom - Enter any character or string you prefer
Enable Helpful Options
- Trim Lines - Removes extra spaces at the start and end of each line
- Remove Empty - Skips blank lines so they don't create extra separators

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.
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.
