Clean up unwanted whitespace in your text. Collapse repeated spaces to a single space or remove them entirely, convert tabs to spaces, or trim leading/trailing whitespace on every line.
Copying text from documents or web pages often brings along runs of repeated spaces, full-width spaces, and tab characters. That extra whitespace can break parsers, cause formatting glitches when pasted into spreadsheets or a CMS, or make diffs noisy. This tool cleans text entirely in your browser without sending anything to a server, so sensitive content stays private.
"Collapse repeated spaces" keeps single spaces between words while tidying up double/triple spacing — ideal for prose. "Remove all whitespace" strips spaces between words entirely, gluing everything into one string, which is useful for identifiers or compact code snippets where no spaces are needed at all. The two modes are mutually exclusive; pick whichever matches your goal.
Tab characters render at different widths across editors, which can make alignment look broken when pasted elsewhere. "Convert tabs to spaces" normalizes every tab to a single space. "Trim leading/trailing space per line" is handy when you paste a multi-line list or log and want to strip stray spaces from the start and end of every line in one pass.
