Why Should You Remove Hard Line Breaks from Pasted Text?
Removing hard line breaks repairs fragmented sentences copied from fixed-width PDF columns, academic papers, and plain-text email wraps so paragraphs reflow naturally across any screen width.
When you copy text from PDF documents, emails, or code terminals, the text often contains artificial hard line breaks at the end of every row. Pasting this text into a Word document, email composer, or website results in broken, ragged sentences that do not reflow properly.
How Does the Line Breaks Removal Algorithm Work?
The engine applies text.replaceAll("\n", " ") (handling CRLF \r\n and LF \n), substituting each line break (U+000A) with an ASCII space (U+0020) so the last word of one line never collides with the first word of the next line.
Text Cleaner replaces all hard line breaks (\r\n, \n, and \r) with a single clean space, turning fragmented sentences into a continuous paragraph without losing words or merging adjacent characters together.
