JavaScript is minified with Terser (compression and identifier mangling, no source map). CSS is minified with CSSO. The HTML mode conservatively removes comments and collapses whitespace, while leaving pre, textarea, script, and style contents untouched. The heavier parsers load only when you press Minify.

About Code Minifier

Minify JavaScript, CSS, and HTML with real parsers and a safe, size-saving result.
