Remove Line Breaks

The Remove Line Breaks tool takes text that is broken across many lines and joins it back into continuous text. It deletes the newline characters, the carriage returns, or both, and replaces each one with a separator you choose: a single space, nothing at all, a comma, a semicolon, or a custom string. Paste the text, pick how the lines should be joined, and copy a clean result in one click.

Press Load sample to see the remove line breaks tool at work. The sample is two paragraphs spread over eight lines, the way text looks when it comes out of a PDF. With the default settings the output is two clean paragraphs, "The quick brown fox jumps over the lazy dog near the river." and "A second paragraph was pasted from a PDF with a hard return on every single line.", with one blank line between them. The label above the output reads "5 breaks removed, 28 words", because the two breaks that form the blank line are kept.

The most common reason a block of text is full of unwanted line breaks is that it was copied from somewhere that wraps every visual line with a hard return. Text pulled out of a PDF, an email, a code comment, or a fixed-width terminal often arrives with a newline at the end of each display line rather than only at the end of each paragraph. Pasting that into a document leaves ragged, prematurely broken lines that no longer reflow. This tool removes those breaks so the words run together as one flowing paragraph again.

The paragraph-aware mode is what makes the result readable rather than a single giant run-on line. With it enabled, blocks that were separated by a blank line stay separate: the tool only flattens the single line breaks inside each paragraph and keeps one blank line between paragraphs. Turn it off when you want every line break gone and the whole input collapsed into one line, which is useful for turning a column of values into a comma-separated list or a single CSV row.

Two clean-up options tidy the output further. Trim strips the leading and trailing whitespace from each line before it is joined, so indentation and stray spaces at the ends of lines do not survive. Collapse spaces reduces any run of spaces or tabs down to a single space, which removes the double spaces that often appear once lines are joined. Both can be toggled independently, and a live counter above the output shows how many line breaks were removed and the new word total.

Everything runs in your browser with JavaScript. Your text is never uploaded, there is no account, and the tool keeps working offline once the page has loaded, so it is safe for private notes, contracts, or anything that should not leave your device. Because the work happens in memory, even very large blocks of text are joined instantly with no upload limit and no server round trip.
