Remove JavaScript Comments

JavaScript supports both line comments (//) and block comments (/* ... */). This tool removes them all in one click using a smart tokenizer that understands strings, template literals, and regular expressions — so a // inside "https://" or a /* inside a regex will never be touched.

Why remove JS comments?

  • Smaller bundles — every byte matters for JS in the critical path.
  • Faster parse time — browsers skip whitespace and comments faster.
  • Cleaner output — remove leftover debug notes and TODOs.
