Frequently Asked Questions
How much can CSS minification save? ▼
Typically 20-50% of file size by removing comments, whitespace between rules, and unnecessary characters. Highly commented or loosely formatted CSS can see even greater savings. Every kilobyte saved improves page load speed.
Does minification change how my CSS works? ▼
No. Minification only removes formatting and comments. The CSS selectors, properties, and values - and therefore the visual rendering - remain completely identical to the original.
What is the difference between minification and compression? ▼
Minification removes whitespace and comments from the source code itself, permanently reducing the file size. HTTP compression (gzip or brotli) is applied by the web server at transfer time, compressing the file for transmission without changing the stored file. Both techniques are complementary and can be used together.
