The Text Cleaner strips out the invisible mess that gets copied along with almost any online paragraph: double spaces, tab stops, non-breaking spaces (U+00A0), zero-width joiners (U+200B–U+200D), stray line breaks in the middle of sentences, and repeated punctuation. It normalises Windows CRLF and old-Mac CR line endings to a single Unix LF so the output stays consistent when pasted into markdown editors, code, or plain-text notes. Under the hood it applies configurable rules in order: collapse runs of horizontal whitespace to one space, trim each line, collapse three or more consecutive newlines to a paragraph break, and optionally drop lines that contain only punctuation. Everything happens in your browser using regular expressions, so a 50-page document is cleaned in milliseconds and never touches a server.
Free, fast, and runs entirely in your browser — no signup, no upload to a server.
