Frequently Asked Questions

What does CSS minification do?

CSS minification removes unnecessary characters like whitespace, comments, and line breaks without changing functionality. It also optimizes the code by removing redundant semicolons and spaces around special characters, resulting in a smaller file size.

How much smaller will my CSS file be?

The size reduction depends on your original CSS. Well-formatted CSS with comments and whitespace can be reduced by 20-40%. The tool shows exact byte savings and percentage reduction for your specific code.

Can I reverse minification?

Yes! Use the beautify mode to format minified CSS with proper indentation and spacing. While comments are lost during minification, the code structure and functionality are preserved and can be made readable again.

Is minified CSS safe for production?

Absolutely! Minified CSS is functionally identical to the original. Browsers parse it the same way. It's a standard practice to serve minified CSS in production for optimal performance while keeping readable versions for development.

Is my CSS code stored anywhere?

No. All processing happens entirely in your browser using JavaScript. Your CSS code is never sent to our servers or stored anywhere. It remains completely private and secure.
