Paste text copied from PDFs, e-books or emails that arrives with hard line breaks and messy spacing. This tool merges lines that were broken mid-paragraph back into flowing paragraphs (blank lines still separate paragraphs), collapses repeated spaces, and can optionally indent each paragraph with two full-width spaces.
It can also insert a space between adjacent Chinese and English/number characters and normalize common ASCII punctuation to its full-width Chinese form. All processing happens locally in your browser.
