Frequently Asked Questions

What is CSS minification and how does it work?

CSS minification compresses stylesheet code by stripping out unnecessary line breaks, indentation, redundant spaces, and code comments. Minification produces compact CSS code that downloads much faster over web networks.

Will minifying CSS change how my web page looks?

No. CSS minification only removes formatting characters that browsers ignore during parsing. CSS rules, selectors, property values, and media queries remain functionally identical.

What compression savings can I expect from CSS minification?

CSS minification typically reduces stylesheet file sizes by 20% to 50%, depending on the original code formatting density, comment volume, and indentation style.

Can I preserve license comments when minifying CSS?

Yes. By default standard multi-line comments are stripped for maximum compression, but you can toggle the comment removal checkbox if you need to keep comments intact.

Is my CSS stylesheet safe and private?

Yes. All CSS minification, whitespace reduction, and stats calculations take place 100% inside your local web browser. Your CSS files and code snippets are never transmitted to any external server.

How do I un-minify or restore CSS back to readable code?

To revert minified CSS back into human-readable code with clean formatting and indentation, use our free CSS Formatter tool.
