Trim JavaScript by removing comments and collapsing whitespace, with a string- and template-literal-aware parser so your code and text stay intact. It is a safe whitespace/comment minifier — for full variable mangling, use your build tool. Runs in your browser.
JavaScript Minifier is a quick, no-nonsense developer utility that runs entirely client-side, so your code and data never leave your machine.
It is string- and comment-aware, so strings, template literals and regex are preserved. Review the output before shipping.
