Frequently Asked Questions

Does minifying CSS affect how my website looks?

No, CSS minification only removes unnecessary whitespace, comments, and formatting. The visual appearance and styling of your website remain exactly the same.

How much can CSS minification reduce file size?

Typical CSS minification reduces file size by 20-60%, depending on how much whitespace and comments the original file contains. Combined with GZIP compression, total reduction can reach 80-90%.

Should I keep the original CSS file?

Yes, always keep your original, readable CSS file for development and maintenance. Use the minified version only in production. Most build tools (Webpack, Gulp) automate this process.
