How much does minification reduce file size?+

Typically 20-40% for well-written CSS. Files with lots of comments and whitespace can see 50%+ reduction.

Does minification affect how CSS works?+

No. Minification only removes whitespace and comments which browsers ignore anyway. The CSS behaves identically.

Can I reverse minified CSS back to readable?+

There is no perfect reversal but CSS beautifiers can add back indentation and line breaks for readability.

Should I always minify CSS?+

Yes for production sites. Keep your original readable CSS in version control and serve the minified version to users.
