Frequently Asked Questions

The minifier uses safe compression techniques that preserve all functionality. However, always test minified code before deploying to production.
This tool outputs minified code without source maps. For production builds with source maps, use a build tool like webpack or Vite.
This tool works with compiled JavaScript. Compile TypeScript to JS using tsc first, then minify it here.
