About the Whitespace Cleaner
This tool cleans whitespace in text: trimming each line, collapsing runs of spaces into one, removing blank lines and normalising line endings between Windows CRLF and Unix LF. Each option is separate so you apply only what you need.
Clean whitespace to fix text that came from somewhere else. Copying out of a PDF leaves double spaces and trailing tabs, pasting from a website brings non-breaking spaces, and moving files between Windows and macOS mixes line endings.
Invisible characters cause visible problems. Trailing spaces break exact-match comparisons and make diffs noisy; non-breaking spaces look identical to normal ones but fail a search; mixed line endings make a file appear entirely rewritten in version control when nothing actually changed.
Each operation is a separate toggle, because collapsing all spaces would destroy indentation in code while trimming line ends is nearly always safe. Everything runs in your browser.
