Remove Line Breaks – Clean Text from PDFs & Paste
Collapse hard line breaks from pasted text. Optional paragraph preservation. Runs in the browser.
About Remove Line Breaks
Output is derived with `useMemo` from your textarea: normalize CRLF/LF, then either flatten all newlines to spaces or keep double newlines as paragraph breaks and collapse single newlines inside each block.
How it works (technical)
`cleanText`: `replace(/\r\n/g, "\n")`, then if not preserving paragraphs, `replace(/\n+/g, " ")` and collapse double spaces.
With **Preserve paragraphs** on: split on `/\n\s*\n+/`, collapse inner `\n` to spaces per block, rejoin with `\n\n`.
Pure string logic—no upload, no NLP.
When to use it

Frequently Asked Questions
Does this upload my text to a server?
No. All cleanup runs in your browser. Your text is not sent to WebTooly or stored by us.
What does “preserve paragraphs” do?
When enabled, double line breaks (blank lines) are kept as paragraph separators. Single line breaks inside a paragraph are turned into spaces so sentences flow normally.
Can I use this for code?
Yes, but flattening code removes line structure. Use single-line flattening only when you intentionally want one line — for example for a compact string or a database field.
