Frequently Asked Questions

Is this minifier as advanced as build tools like Terser?
This is a lightweight whitespace and comment-stripping minifier. For advanced minification with variable renaming and dead-code elimination, dedicated build tools are recommended.
Could minification break my code?
This tool is conservative and focuses on safe whitespace/comment removal, but always test minified code before deploying to production.
Does it support ES6+ syntax?
Yes, the minifier processes text generically and works with modern JavaScript syntax including arrow functions and template literals.
