Frequently Asked Questions
Does minification change how CSS works?
No. Minification only removes unnecessary characters (whitespace, comments, etc.) while preserving all functionality. Your CSS will work exactly the same.
What's the average reduction in file size?
Typically 20-40%, but it can be higher for CSS with heavy comments and formatting. The exact reduction depends on your original CSS structure.
Is my CSS code sent to any server?
No! All minification happens in your browser. Your CSS code never leaves your device, ensuring complete privacy.
Should I minify CSS for development?
No, keep CSS formatted during development for readability and debugging. Minify only when preparing for production deployment.
