How It Works

A state machine walks the code outside of strings, removing line and block comments and collapsing whitespace while preserving string literals intact.

HTML gets its comments stripped and inter-tag whitespace collapsed. The tool reports the original and minified sizes plus the percentage saved.

Minification is conservative to avoid breaking your code, and everything runs locally.
