🎨 What is CSS Minification?

Minified CSS files are smaller, load faster, and improve website performance. It's an essential optimization technique for production websites.

❓ Frequently Asked Questions
How much can CSS minification reduce file size?
Typically 20-40% reduction, depending on your CSS structure. Files with lots of comments and whitespace see bigger savings. Combined with gzip compression, you can achieve 70-80% total reduction.
Will minification break my CSS?
No! Minification only removes unnecessary characters while preserving functionality. However, always test your minified CSS to ensure everything works as expected.
Should I minify CSS for development?
No. Keep CSS readable during development for easier debugging. Only minify for production deployments. Use beautified CSS during development and testing.
Can I reverse minification?
Yes! Use our "Beautify CSS" feature to format minified CSS back into a readable format. However, comments are permanently removed during minification.
Is my CSS data secure?
Absolutely! All processing happens entirely in your browser. Your CSS code never leaves your device and is not sent to any server.
