CSS Minifier & Beautifier
Minify CSS to reduce file size or beautify it for readability. Everything runs in your browser — your code stays private.
What Is CSS Minification?
CSS minification is the process of removing unnecessary characters from CSS source code without changing its functionality. This includes stripping comments, whitespace, newlines, and redundant separators. The result is a smaller file that loads faster in the browser.
Minified CSS reduces bandwidth usage and improves page load times, which directly affects user experience and search engine rankings. Google considers page speed as a ranking factor, so serving minified CSS is an easy SEO win.
When to Minify vs. Beautify
Minify your CSS before deploying to production. Smaller files mean faster page loads and lower bandwidth costs. This is especially important for mobile users on slow connections.
Beautify CSS when you need to read or debug minified code. If you receive a compressed stylesheet from a third-party library or need to inspect production CSS, the beautifier reformats it with proper indentation and line breaks.

How Much Can CSS Minification Save?
Typical CSS minification reduces file size by 15-30% for well-written stylesheets. Heavily commented or formatted files can see savings of 40% or more. Combined with gzip compression on the server, total transfer size reductions of 70-85% are common.
