Everything you need to know about CSS minification.

Will minifying my CSS break my website?

How much space can I save with this tool?

On average, CSS files can be reduced by 20% to 50% depending on the amount of comments and spacing in the original file.

Does this tool support CSS variables?

Yes, our minifier preserves modern CSS features like variables, custom properties, and grid layouts.

Should I minify CSS for development?

It's best to keep your development files unminified for readability and only minify them for your production environment.

What happens to @import rules?

@import rules are preserved and correctly formatted, ensuring your stylesheet dependencies remain intact.
