Remove Line Breaks from Any Text
Remove line breaks instantly to turn messy multi-line text into one clean, continuous line. It fixes the unwanted newlines you get when you copy from PDFs, emails, websites, or documents, without retyping a thing.
You control exactly how lines are joined: replace each break with a Space, with Nothing, with a Comma or Semicolon, or with any Custom separator you type. Extra options let you trim stray whitespace and skip empty lines, and a batch mode cleans many files at once.
How to Remove Line Breaks
Add your text
Paste or type your multi-line text into the Input panel on the left, or use the Paste button to pull it from your clipboard.
Choose how lines join
Pick a Join with option: Space (the default), Nothing, Comma, Semicolon, or Custom to enter your own separator.
Fine-tune the cleanup
Turn on Trim Lines to strip leading and trailing spaces, and Remove Empty to skip blank lines so they don't add extra separators.
Copy or download
The single-line result appears in the Output panel as you go. Copy it to your clipboard or Download it as a text file.
To clean several files in one go, open Batch Process Files, drop your files onto the upload area (or click to browse), set a filename Suffix (default -cleaned), then download files one at a time or use Download All.

Frequently Asked Questions
How do I remove line breaks and replace them with spaces?
Paste your text into the Input panel and keep Space selected as the Join with option (it's the default). Every line break becomes a single space. Leave Trim Lines on to also clear extra whitespace from each line.
How do I stop words from merging together?
Choose Space as the separator so a space is inserted wherever a line break was. The Nothing option joins lines with no character between them, which is what causes words to run together, so avoid it unless that's what you want.
Can I join lines with no separator at all?
Yes. Select Nothing and the lines are joined directly with nothing between them. This is handy when line breaks have split a single word or when you're stitching code strings back together.
How do I remove line breaks copied from a PDF or email?
Paste the copied text into the Input panel exactly as it is. Use the Space separator and turn on both Trim Lines and Remove Empty to collapse the broken lines and stray blank lines into one clean paragraph.
Can I use a multi-character separator?
Yes. Select Custom and type any string you like, such as | , - , or longer text. The tool inserts your exact input between the lines.
Why does my output have extra spaces?
That usually happens when lines have trailing spaces or when blank lines create consecutive separators. Enable both Trim Lines and Remove Empty for clean output with single, consistent spacing.
What file types can I upload for batch processing?
The batch uploader accepts common text-based files: .txt, .csv, .md, .log, .json, .xml, .html, .css, and .js. Binary files like images or PDFs aren't supported.
Is my text uploaded anywhere?
No. Everything runs locally in your browser with JavaScript. Your pasted text and uploaded files stay on your device and are never sent to a server, so you can safely clean up sensitive documents. Your settings are saved only in your own browser.
