How to use this tool
- Paste text containing unwanted hard line breaks.
- Choose whether blank lines should preserve paragraph boundaries or whether everything should become one paragraph.
- Run Join lines and review lists, headings, and words broken at a hyphen.
Understanding the output
A newline inside a retained paragraph becomes a space. In the one-paragraph mode, blank lines are joined too. The tool removes whitespace around the replaced breaks, but it does not rewrite words, repair OCR errors, or infer the original page layout.
For repeated spaces left by copying, use the Whitespace Cleaner and review the cleaned passage before replacing the original.
A wrapped sentence and a separate paragraph
A sentence wraps followed by a newline and onto another line. becomes A sentence wraps onto another line. A blank line before the next paragraph stays as a paragraph boundary in the default mode.
Recognize a hard wrap before removing it
A visual wrap happens automatically when a text box is narrow; it does not insert a newline into the text. A hard wrap is an actual line-ending character, often copied from a PDF or a plain-text email. This tool changes only the latter. If a paragraph already flows when the window is resized, there may be nothing to remove.
For multi-column documents, verify the reading order before joining lines. A copy operation may alternate between columns, and joining the resulting text cannot restore the correct sequence of sentences.
Protect meaningful structure
Lists, addresses, headings, and poetry often use line endings intentionally. Joining these lines can make the result harder to understand even if it appears shorter. Process one section at a time when a document mixes prose with structured blocks. Hyphenated line endings also need review: a hyphen may be part of the word or only a printed line-break convention, and automatic removal could change its meaning.
Method and supported input
The tool normalizes line endings, separates blank-line paragraphs in the default mode, and replaces remaining newline runs with ordinary spaces.
- Blank lines are the paragraph boundaries worth keeping in the default mode.
Limitations
- It does not repair OCR mistakes or column ordering.
- Hyphens are retained because their meaning cannot be inferred reliably.
Common questions
Why did a bullet list become a sentence?
Each line break is treated as a join point. Keep lists out of the input when their line structure matters.
Can this join only one paragraph?
Yes. Paste just that paragraph, or use the default mode to retain blank-line separators between several paragraphs.
