Join copied lines, remove empty lines, preserve paragraph spacing, or normalize line endings. Your text stays private in your browser.
Processing stays in this browser. Press Escape, then Tab, to move focus out of the editor.

Select one primary operation, then apply only the cleanup options you need.
Replace with spaces: Replace each logical line break with one normal space.

Enter or paste text, then choose how its line breaks should be handled.
Remove Line Breaks cleans text copied from PDFs, documents, emails, websites, and narrow text columns. Choose one predictable operation to join lines, remove empty lines, preserve paragraph spacing, or normalize line-ending characters.
The source remains unchanged in the editor. Every option produces a separate in-memory result that you can review and copy without uploading the text.
Joining operations replace or remove CRLF, LF, and lone CR logical separators. Existing spaces remain exact unless trimming is enabled.
Turn each logical separator into one U+0020 space for readable paragraphs.
Delete separators without inserting text, while retaining existing adjacent spaces.
Create a comma-and-space list without silently trimming source lines.
Insert short literal Unicode text such as a pipe or semicolon at each joining boundary.
These operations retain the line structure instead of joining it. Ignore Blank Lines never participates in these modes.
Delete every empty or horizontal-whitespace-only physical line.
Keep at most one blank line in a run so paragraph boundaries remain visible.
Convert recognized separators to LF or CRLF without rewriting line content.
The shared Text Line Parser recognizes CRLF as one logical delimiter and also recognizes LF and lone CR. It preserves physical lines, blank lines, mixed separators, and trailing delimiters so the selected operation can construct its own exact output.
Unicode line separator U+2028 and paragraph separator U+2029 are treated as ordinary content. Browser textarea controls may normalize pasted line endings before JavaScript receives them, so no browser tool can promise recovery of an already-normalized source style.
The engine first identifies physical lines, then optionally trims horizontal whitespace and removes boundary blank lines before applying the selected primary operation. This fixed order keeps combinations deterministic.
Ignore Blank Lines is narrower: it participates only when joining with spaces, no replacement, commas, or custom text. Remove Empty Lines is a separate primary operation and does not depend on that checkbox.
Removing a separator can merge words. Use spaces when the source does not already contain boundary spacing.
A line break separates physical lines. A blank line is an empty or horizontal-whitespace-only physical line.
A browser may normalize textarea input before the utility sees it. Review normalized output when an external system requires an exact convention.

CRLF, LF, and lone CR handling is a documented TextCraftHub parser contract. Horizontal-whitespace classification follows ECMAScript whitespace definitions while keeping Unicode line and paragraph separators as ordinary content for this utility.
No. The source and processed result remain in your browser. Remove Line Breaks does not upload the text, add cloud storage, or save persistent history.
Yes. Replace with spaces converts each recognized CRLF, LF, or lone CR separator into one normal space while preserving every other character unless you enable a cleanup option.
Yes. Comma mode uses a comma followed by a space. Custom replacement uses up to 100 Unicode code points literally, so text such as a pipe, semicolon, tab, or short label is not interpreted as an escape sequence.
An empty line contains no characters or contains only ECMAScript horizontal whitespace such as spaces and tabs. Unicode line separator characters U+2028 and U+2029 remain ordinary content for this utility.
It skips blank physical lines only while joining with spaces, no replacement, commas, or custom text. It has no effect on Remove Empty Lines, Collapse Blank Lines, or Normalize Line Endings.
Remove Empty Lines deletes every empty or horizontal-whitespace-only line. Collapse Blank Lines keeps at most one blank line in each run, which preserves paragraph separation.
Yes. Normalize Line Endings converts recognized separators to LF or CRLF. Browsers can normalize textarea line endings before page code receives them, so the utility cannot recover an original style the browser has already changed.
No. Trim Every Line removes supported horizontal whitespace only from the beginning and end of each physical line. Internal spacing and non-whitespace characters remain unchanged.
No. Large results show a preview of 500 complete grapheme clusters, but Copy always uses the complete transformed result held in memory.
The editor accepts up to 100,000 Unicode code points. Processing is deferred while typing so the editor remains responsive, and all work stays in the browser.
