Frequently Asked Questions
How much can CSS minification reduce file size?
Typically 30-60% depending on the original CSS formatting. Well-commented, indented CSS sees the biggest reduction. Combined with Gzip/Brotli server compression, total reduction can reach 80%+.
Does minification affect CSS functionality?
No. Proper minification only removes non-functional characters. All selectors, properties, and values remain functionally identical. Always keep an unminified source copy for debugging.
Can I use this in production?
This tool is designed for development and testing. For production use established libraries with security audits.
