FAQ
How much does CSS minification reduce file size?
Typically 30–60% reduction. A 50 KB CSS file often minifies to 20–30 KB. Combined with gzip compression on the server, effective savings can exceed 80%.
Is minified CSS still valid CSS?
Yes. Minification only removes whitespace, comments, and optional characters. The browser parses it identically to the original.
Should I minify CSS in development?
No — always keep readable source CSS in development. Use a build tool (Vite, webpack, PostCSS) to auto-minify for production. This tool is for one-off minification or when build tools aren't available.
