Minify CSS code for faster page loads.
The CSS Minifier removes unnecessary whitespace, comments, and redundant characters from CSS files to reduce their size for production. Smaller CSS files load faster, especially important for mobile users on slow connections. Minification typically reduces CSS file size by 30–50%. The minified output is functionally identical to the original — all styles are preserved. Use expanded, readable CSS in development; deploy minified CSS in production.
Minification removes whitespace and comments from the source code — the result is still readable (barely). Compression (gzip/brotli) is a binary encoding applied by the web server at transfer time. Both can be used together: minify first, then serve with gzip compression.
No — the browser interprets minified CSS identically to formatted CSS. Shorthand property merging (e.g. combining margin-top, margin-right etc. into margin: shorthand) is a more aggressive optimization that some minifiers perform.
No. Minified CSS is impossible to debug because line numbers and readable property names are lost. Use formatted CSS in development with source maps; minify only for production builds.
