What Is Code Minification?
Minification removes unnecessary characters from source code (whitespace, comments, line breaks) without changing functionality. The result is a smaller file that loads faster in browsers, improving page speed and Core Web Vitals scores.
How Much Can You Save?
Typical savings range from 20-60% depending on the code. The tool shows you exact before/after sizes and the percentage reduction. For production deployments, minification is a standard best practice alongside gzip compression.
