Remove Line Breaks From Text
Strip newlines and tidy whitespace fast. Join lines with a space, nothing, or a custom separator, then copy. All local, nothing uploaded.
What this tool does
This tool removes line breaks and cleans up whitespace entirely in your browser. Paste
text, choose what to replace each line break with (a space, nothing, or a custom
separator), and the result updates live as you type or change options. Optional toggles
let you collapse runs of spaces into one, trim each line, remove blank lines, and trim the
whole result. It handles both Windows (\r\n) and Unix (\n) line
endings, so pasted text from anywhere is cleaned the same way.
Privacy: Runs entirely in your browser. To verify, open DevTools and watch the Network tab: zero requests.
How to use it
Paste or type your text in the box. Pick a line-break replacement: Space
turns wrapped lines into one flowing paragraph, Nothing glues the lines
together with no gap, and Custom lets you type your own separator
(the escapes \n, \r, and \t become a newline,
carriage return, and tab). Toggle the clean-up options as needed, then click
Copy result. For example, three lines reading a, b, and c become
a b c with Space or abc with Nothing.
Common use cases
- Joining a hard-wrapped paragraph copied from a PDF or email back into a single line.
- Stripping newlines out of a value before pasting it into a spreadsheet cell or CSV field.
- Removing blank lines and trailing spaces from a messy list or log.
- Flattening a multi-line code snippet, token, or key into one line.
- Turning a list of lines into a comma-separated string with a custom separator.
Common pitfalls
- Space versus nothing. Replacing with a space keeps words readable
(
a b c); replacing with nothing concatenates them (abc). Pick nothing only when you truly want the lines glued together, such as rejoining a split key or URL. - Blank lines are not the same as line breaks. Remove blank lines keeps single newlines between content lines; it does not flatten everything onto one line. Choose a Space or Nothing replacement if you want a single line.
- Custom separators are literal. A custom separator is inserted exactly
as typed, except that the escapes
\n,\r, and\texpand to a newline, carriage return, and tab. - Collapse touches spaces and tabs only. Collapsing multiple spaces squeezes spaces and tabs into one, not other characters, and it runs after the line breaks have been replaced.
Frequently asked questions
- How do I remove line breaks from text?
- Paste your text in the box, then choose what to replace line breaks with: a space, nothing, or a custom separator. The cleaned result appears live below and updates as you type or change options. Click Copy to grab it. Nothing is uploaded; the work happens in your browser.
- What is the difference between replacing line breaks with a space and with nothing?
- Replacing with a space joins wrapped lines into flowing text, so three short lines reading a, b, and c become "a b c". Replacing with nothing concatenates the lines directly into "abc", which is useful for rejoining a value, key, or code that was split across several lines.
- Does this handle Windows (CRLF) line endings?
- Yes. The tool normalizes Windows CRLF and old Mac CR endings to a single newline before processing, so text pasted from any operating system is cleaned the same way. You will not see stray carriage-return characters left behind in the output.
- What does remove blank lines do?
- Remove blank lines drops any line that is empty or contains only whitespace, while keeping the line breaks between the lines that still have content. So a block with two empty lines between paragraphs collapses down to adjacent lines with no gaps, without flattening everything onto one line.
- What is the difference between trim each line and collapse multiple spaces?
- Trim each line removes leading and trailing whitespace from every individual line. Collapse multiple spaces squeezes any run of spaces or tabs anywhere in the text down to a single space. You can turn on both to tidy messy indentation and double spaces at the same time.
- Can I use my own separator instead of a space?
- Yes. Pick Custom and type any separator, such as a comma and space to turn lines into a comma-separated list. The escape sequences backslash-n, backslash-r, and backslash-t are interpreted as a newline, carriage return, and tab, so you can also keep or reshape the line breaks.
- Is my text sent to a server?
- No. All of the cleaning runs in plain JavaScript on your machine, so your text never leaves the browser. You can confirm it by opening DevTools and watching the Network tab while you edit: there are zero requests, and the tool keeps working offline once the page has loaded.
