Frequently Asked Questions

Will CSS minification break my styles?
No, minification only removes unnecessary characters and optimizes values while preserving functionality. The visual appearance of your styles remains exactly the same.
How much can I expect to reduce file size?
Typical reduction is 20-40% depending on your CSS structure. Highly commented or formatted CSS can see even greater reductions.
Are CSS variables and modern features supported?
Yes! The minifier preserves CSS custom properties (variables), calc() functions, CSS Grid, Flexbox, and other modern CSS features.
Should I minify CSS for development?
No, keep readable formatting during development. Minification is best applied during your build process or before production deployment.
Can I preserve certain comments in minified CSS?
Important comments (like copyright notices) starting with /*! are automatically preserved even when comment removal is enabled.
