JavaScript Minifier
Compress JavaScript safely — no side effects on strings or eval.
About the JavaScript Minifier
Compress JavaScript by removing comments and insignificant whitespace while leaving string literals, regular expressions, and eval contents untouched — a safe, side-effect-free compression.
Frequently asked questions
Does it rename variables like a bundler?
No. This minifier is deliberately conservative — whitespace and comments only — so nothing can change behaviour.
Should I still use a bundler for production?
Yes — esbuild/terser rename and tree-shake. This tool is for quick one-off compression.
