Frequently Asked Questions

FAQs about CSS Minify

What does CSS minification do?

Minification removes comments, extra whitespace, newlines, and redundant characters to produce the smallest valid CSS file.

Are CSS comments removed?

Yes. Both block comments (/* ... */) and any inline spacing are stripped during minification.

Will minified CSS still work in browsers?

Yes. Minified CSS is functionally identical to formatted CSS — browsers parse both the same way.

How much size reduction can I expect?

Typically 20–50% reduction depending on how much whitespace and how many comments the original contains.

Is my data safe?

All processing runs entirely in your browser. No CSS is ever sent to a server.
