Choose what gets removed

Whitespace collapsing uses conservative single spaces. Disable it when CSS white-space rules or templates depend on exact spacing. Preformatted content, scripts, and styles are not minified. License comments beginning with !, conditional comments, server-side includes, and ToolPixels markers are kept. Output is not sanitized: only use it in a trusted context.

Only the required local processor is loaded when you run the tool. Large jobs run in a cancellable background worker. Source and results remain text, including scripts, markup, and URLs.
