Frequently Asked Questions

What does the CSS minifier do?

It removes CSS comments, collapses multiple spaces into one, removes spaces around special characters like curly braces and semicolons, and removes trailing semicolons before closing braces.

Can I minify multiple CSS files at once?

You can paste CSS from multiple files into the textarea and minify it all at once. The tool processes all CSS in the input.

Is my CSS uploaded to a server?

No. All processing happens entirely in your browser. Your code never leaves your device.

What compression ratio can I expect?

Typical CSS minification saves 20-40% of the original size, depending on how much whitespace and comments your CSS contains.
