About This Tool
Documentation
What does this tool do?
A high-performance CSS compression engine. Strips block and line comments, collapses whitespace, shortens 6-digit hex codes to 3-digit equivalents, strips redundant unit qualifiers from zero values (`0px` -> `0`), and computes exact payload byte savings and compression ratios.
When should you use it?
Use this tool before publishing production stylesheets to minimize bandwidth consumption, speed up browser First Contentful Paint (FCP), and optimize static asset caching.
