CSSO
A CSS minifier that performs structural optimizations to significantly reduce file size.
What is CSSO?
CSSO is a CSS minifier and optimizer that reduces CSS file size through structural transformations. It performs cleaning, compression, and restructuring of CSS code to eliminate redundancy and produce minimal output. Unlike basic minifiers, it analyzes and merges CSS rules for maximum efficiency.
Frontend developers and build engineers who need to optimize CSS for production websites and applications, especially those using modern build tools like webpack, Gulp, or PostCSS.
Developers choose CSSO for its advanced structural optimizations that often produce smaller CSS than other minifiers. Its integration with CSSTree provides reliable parsing, and its plugin ecosystem makes it easy to incorporate into existing workflows.
