Remove Line Breaks
Strip line breaks and newlines from text — join lines, collapse spaces, and clean up in your browser.
About the Remove Line Breaks
The Remove Line Breaks tool strips the newlines out of any block of text and rejoins it into clean, continuous lines. Text copied from PDFs, emails, code comments, spreadsheets, and web pages is often riddled with hard line breaks that were only there to fit a column width. Paste that text somewhere new and the breaks come along too, leaving awkward gaps in the middle of sentences. This tool clears those breaks instantly, and it runs entirely in your browser — nothing you paste is uploaded, stored, or sent anywhere.
You control exactly how the lines are rejoined. Replace every break with a single space so words don't run together, or join with nothing at all to concatenate fragments directly. Optional cleanups let you collapse runs of extra spaces down to one, trim stray whitespace from the start and end of each line, or switch to a gentler mode that deletes only the blank lines while keeping your real paragraph structure intact.
How to use
- Paste your text into the Input box. The cleaned result appears in the Output box below and updates the moment you type, paste, or change an option.
- Pick a mode. "Remove all line breaks" flattens the whole text into one continuous block. "Remove empty lines only" keeps your line structure but deletes blank lines between paragraphs.
- Choose how to join (in "remove all" mode). Select "A space" to put a space where each break used to be, or "Nothing (concatenate)" to fuse the pieces together with no gap.
- Toggle the cleanups. "Collapse multiple spaces into one" tidies double or triple spaces, and "Trim each line" removes leading and trailing whitespace so the join is clean.
- Copy or clear. Press "Copy result" to send the output to your clipboard, or "Clear" to empty the input and start over.
When each option helps
Reflowing a paragraph copied from a PDF is the classic case: choose "remove all line breaks," join with a space, and keep both cleanups on. That turns a column of chopped-up lines back into a flowing paragraph. Joining with nothing is handy when you've copied a long token — a URL, hash, or serial number — that got wrapped across several lines and needs its pieces glued back together. The "remove empty lines only" mode is best when you want to keep your paragraphs on separate lines but delete the double-spacing between them, such as tightening up a pasted list or a block of notes.
Every transformation happens locally in JavaScript, so it is instant and completely private — the tool handles both Windows-style \r\n and Unix-style \n line endings automatically, so text from any operating system is cleaned correctly.
Frequently asked questions
What exactly is a "line break"?
A line break is the invisible character (or pair of characters) that ends one line and starts the next when you press Enter. On Windows it is a carriage return plus a line feed (\r\n); on macOS and Linux it is a single line feed (\n). This tool detects all of these forms and removes or replaces them consistently, so you never have to worry about which system the text came from.
Does the tool send my text anywhere?
No. All processing runs on your own device using in-browser JavaScript. Your text is never uploaded to a server, saved, or logged. Close the tab and everything you pasted is gone.
What's the difference between joining with a space and joining with nothing?
Joining with a space puts one space wherever a line break used to be, which is what you want for normal sentences so words stay separated. Joining with nothing removes the break entirely with no gap, which is right for reassembling something that was split mid-word, like a long link or code string.
What does "Remove empty lines only" do?
Instead of flattening everything into one line, this mode keeps your existing line breaks but deletes any line that is blank (or contains only whitespace). Use it to close up the extra vertical spacing in a list or document while preserving the paragraph layout.
Will it fix double spaces too?
Yes, if you enable "Collapse multiple spaces into one." After the line breaks are removed, any run of two or more spaces is reduced to a single space. Combine it with "Trim each line" to remove leftover whitespace at the edges of each line for the cleanest possible result.
Is there a size limit on the text?
There is no fixed limit — because everything runs in your browser you can paste anything from a single sentence to a very large document. Extremely large inputs may take a brief moment to process, but nothing is capped or truncated.
