ToolBench runs this tool entirely in your browser. Your file or text is processed on your own device using JavaScript — nothing is uploaded to a server, nothing is stored, and there's no sign-up wall between you and the result. That's true of every one of the 500+ tools on this site, from PDF utilities to unit converters.
