How it works
Minification strips comments and unnecessary whitespace from your JavaScript entirely in your browser — no libraries, no uploads. It safely preserves strings, template literals and regex literals. For advanced compression (variable renaming, dead-code removal), a build-time tool like Terser or esbuild goes further, but this covers the everyday need of shrinking a script to paste or ship.
