About Code Minification

What is Minification?

Code minification removes unnecessary characters (whitespace, comments, newlines) from source code without changing functionality, reducing file size for faster loading.

Supported Languages

JavaScript, CSS, HTML, JSON, and XML files. Each language has optimized minification rules to ensure maximum compression while maintaining code integrity.

Privacy & Security

All processing happens locally in your browser. Your code never leaves your device, ensuring complete privacy and security of your source code.

Best Practices

Always test minified code before deployment. Keep original source files for debugging. Use minification as part of your build process for production.
