How it works

The minifier removes // and /* */ comments outside of strings, collapses runs of whitespace, and trims spaces around operators and punctuation. It does not rename variables, so the output stays readable enough to debug.

Frequently asked questions

Does this mangle variable names?

No. This is a safe whitespace-and-comment minifier. For aggressive name mangling, run a build-time tool such as esbuild or Terser.

Will it break template literals?

Strings, template literals, and regular expressions are detected and left untouched, but always test the output before shipping.

Comments

Comments aren't enabled yet. When you're ready, this is where a service like Giscus, Disqus, or a custom form would go — the slot is already reserved on every tool page.
