Tentang Code Minifier

Every kilobyte counts on slow connections, and minification — removing comments, line breaks and redundant whitespace — is the cheapest performance win available. Paste HTML, CSS or JavaScript and this tool produces a compact production build in milliseconds, reporting the size before and after and the percentage saved. It performs safe, conservative transformations: aggressive renaming is intentionally avoided so your code behaves exactly as it did.

Is this minifier safe for production code?

It applies conservative, well-understood rules only. For large codebases, bundlers like esbuild, Terser or CSSNano offer deeper optimisation — this tool is ideal for quick, one-off files.

Why minify at all?

Smaller files download and parse faster, which improves page speed, Core Web Vitals and indirectly your search rankings.
