Remove Line Breaks — Free Line Break Remover Online
A column of text copied from a PDF, an email forwarded through three clients, a document exported from a legacy system — they all arrive with a hard line break at the end of every visual line. Looks like a paragraph, but it's actually dozens of short separate lines. This line break remover joins them back into flowing prose in one click: every single newline becomes a space, while double newlines (true paragraph breaks) are preserved. No character limit, runs in your browser.
What Is Remove Line Breaks?
A remove line breaks tool joins all the lines in your text into a single continuous paragraph by replacing newline characters with a space (or removing them entirely). Text copied from PDFs, email clients, and certain document formats often arrives with hard line breaks at the end of every visual line — a relic of fixed-width formatting that was baked into the source. This creates a paragraph that looks wrapped in the original but is actually composed of dozens of separate short lines with break characters.
The result in a CMS or word processor is a wall of text with unwanted paragraph breaks. You end up with each original line becoming its own paragraph, requiring extensive manual cleanup. This tool handles the entire cleanup in one pass: all line breaks within a paragraph are removed and replaced with spaces, while double line breaks (true paragraph separators) can optionally be preserved to maintain paragraph structure.

Key Features
Single newlines (the hard-wrapped ones) are replaced with a space. Double newlines (actual paragraph breaks) are preserved — your document structure stays intact.
Windows (\r\n) and Unix (\n) line endings are both normalized. Pasted text from any platform or tool is handled correctly without extra configuration.
A space is inserted at every removed line break to prevent "wordword" joining. If a line already ended with a space, run Remove Extra Spaces afterward to clean the double-space.
Nothing is sent to a server. Works on full documents — a few sentences or a 10,000-word paste. No account, no usage cap.
When to Use Remove Line Breaks
Use when copying text from PDFs or presentations where artificial line breaks break the reading flow.
Multiple spaces left after joining are automatically collapsed to a single space.
Who Should Use This Tool?
Fix PDF-to-text conversion output where every visual line break becomes a hard newline, fragmenting paragraphs before importing to a CMS.
Clean up text email copy that arrives with hard-wrapped line breaks at column 72 before reformatting for HTML email templates.
Join multi-line text output from logs, API responses, and legacy systems into single-line strings for downstream processing.
Key Use Cases
- →Fix PDF copy-paste where each visual line becomes a separate line in text output, breaking paragraph structure — PDFs store text at fixed x/y coordinates, so every line ends with \n even mid-sentence. Removing line breaks and following up with Remove Extra Spaces restores flowing prose.
- →Clean hard-wrapped email text that arrives with line breaks at column 72 or 998 (RFC 2822) before converting to HTML email in Mailchimp, Klaviyo, or HubSpot — hard-wrapped plaintext produces narrow columns of text in HTML templates.
- →Join multi-line terminal or API output into a single line for parsing — curl, jq, and Python scripts often return multi-line output that needs to be on one line for downstream processing or logging.
- →Prepare text scraped from legacy HTML where BeautifulSoup or Scrapy extracted
tags as newlines — BeautifulSoup's get_text(separator="\n") produces fragmented lines that need rejoining before analysis. - →Convert multi-line address blocks from CRM or ERP exports into single-line formatted strings for database fields that expect one-line addresses.
Remove Line Breaks vs Other Formats
How this tool compares to related approaches and methods
| Method / Format | Best For |
|---|---|
| THISRemove Line Breaks (this tool) | Joining hard-wrapped PDF paragraphs, plain-text email (RFC 2822), and legacy document copy-paste into flowing prose — paragraph breaks (double newlines) optionally preserved |
| Remove Empty Lines | Removing blank lines between content without joining the non-blank lines — keeps each line separate, just removes the gaps |
| Remove Extra Spaces | Collapsing double spaces that often appear AFTER removing line breaks — the two tools are frequently used together in sequence |
| Strip HTML Tags | Removing HTML markup entirely — line breaks from <br>/<p> tags are removed along with all other tags; better for HTML source than for already-extracted plaintext with \n characters |
Remove Line Breaks Rules: How It Works
- →Single newlines (\n) replaced with a space — words reunite correctly
- →Windows line endings (\r\n) handled the same way
- →Result: a continuous paragraph from multiple short lines
- →A space is inserted where the break was to prevent word-joining ("wordword")
- ×Double newlines (paragraph breaks) — preserved to keep paragraph structure
- ×Content between lines — no words are deleted, only the breaks
- ×Spaces already present at line ends — may produce double spaces (run Remove Extra Spaces after)
- ×Code, YAML, or CSV — never use on structured text where line breaks are meaningful

This Converter vs Manual Methods
Why use this tool instead of doing it by hand?
| Method | Limitation |
|---|---|
| Word Find & Replace (Ctrl+H, "^p" → " ") | Only works within Word; requires knowing the ^p paragraph mark code; doesn't easily distinguish single vs double newlines |
| Python text.replace("\n", " ") | Requires a Python environment; also removes paragraph breaks (\n\n) unless you handle double newlines separately with a multi-step approach |
| Notepad++ Find & Replace with regex (\n → space) | Requires Notepad++ and knowing to enable regex mode; \r\n vs \n handling varies by document |
| Google Docs Edit > Find & Replace | Doesn't support newline characters in the find field without a script; not practical for plain-text pasted content |
| ✓ BESTThis converter | None — instant, handles both \n and \r\n, preserves paragraph breaks, no environment required |
Common Mistakes & Pro Tips
- !Removing ALL line breaks including paragraph breaks — if your document has distinct paragraphs, check whether the tool preserves double-line-break paragraph separators or removes everything. Merging all paragraphs into one block produces an unbroken wall of text that requires re-editing to restore paragraph structure.
- !Removing line breaks from code, YAML, CSV, or Markdown — line breaks are structurally meaningful in Python (indentation), YAML (hierarchy), CSV (row separators), and Markdown (list items, code fences). Removing them breaks the format. Only use this tool on natural-language prose, not structured text formats.
- !Forgetting to follow up with Remove Extra Spaces — when a line ends with a trailing space before the newline, removing the newline and adding a space creates a double space at the join point. Always run Remove Extra Spaces after removing line breaks when preparing text for a CMS or document.
Frequently Asked Questions
Everything you need to know about Remove Line Breaks
Why does pasted text from a PDF have line breaks in the wrong places?
+
PDFs store text in a fixed-layout format where each line of text is positioned at specific x/y coordinates on the page. When you copy text, the PDF reader extracts it line by line and adds a \n character at the end of each visual line — even mid-sentence. The paragraph reflow behavior is lost because PDFs were designed for print, not for text extraction. The hard line breaks reflect the page column width, not sentence or paragraph boundaries.
What is the difference between a line break and a paragraph break?
+
A line break (\n) ends the current line and continues in the same paragraph. A paragraph break (\n\n — two consecutive newlines) ends the paragraph and starts a new one with visual spacing above. PDFs and hard-wrapped email (RFC 2822 column-72 wrapping) use single newlines where the text should just flow. This tool replaces single newlines with spaces while optionally preserving double newlines to keep paragraph structure intact.
Will the tool add a space where the line break was?
+
Yes — a space is inserted at each removed line break to prevent word-joining ("wordword" instead of "word word"). If the line already ended with a space before the break, the result will have a double space at the join point. Run Remove Extra Spaces afterward to collapse any double spaces introduced this way — the two tools are commonly used in sequence.
Can I use this for SQL or code formatting?
+
No — do not use on structured text. SQL query formatting, Python indentation, YAML hierarchy, CSV row structure, and Markdown list items all rely on specific line breaks for parsing and readability. Removing line breaks from code will produce unreadable or syntactically invalid output. For SQL, use a dedicated SQL formatter (sqlfmt, pgFormatter). For code, use your editor's Format Document (VS Code: Shift+Alt+F).
How do I handle Windows (\r\n) vs Unix (\n) line breaks?
+
Windows text files use carriage return + newline (\r\n, also called CRLF) while Unix/macOS use just \n (LF). Pasted text from Windows tools, legacy email clients, and some APIs may use CRLF. This tool normalizes both — it strips \r\n and \n consistently. If you're handling this in code: Python's universal newline mode (open(file) without "b") handles both; JavaScript str.replace(/\r\n|\n/g, " ") covers both explicitly.
What is RFC 2822 hard wrapping and why does it affect my email copy?
+
RFC 2822 (the email message format standard) recommends lines of 998 characters or fewer, and many plain-text email clients historically wrapped at 72 or 76 characters to ensure readability in fixed-width terminal clients. When you receive or copy plain-text email, those hard line breaks are literal \n characters in the text. This is why a paragraph of email copy arrives as dozens of short lines rather than one flowing paragraph. Removing line breaks restores the prose for use in HTML email templates.
How do I remove line breaks in Python, JavaScript, or Excel?
+
Python (preserve paragraphs): import re; re.sub(r"(?<!\n)\n(?!\n)", " ", text) — replaces single newlines but keeps double ones. Python (simple, removes all): text.replace("\n", " "). JavaScript: str.replace(/(?<!\n)\n(?!\n)/g, " ") — lookbehind/ahead to preserve paragraphs; or str.replace(/\n/g, " ") to remove all. Excel: no direct function — use SUBSTITUTE(A1, CHAR(10), " ") where CHAR(10) is the newline character. Word: Ctrl+H → Find "^p" (paragraph) or "^l" (manual line break) → Replace with a space.
