CSS Minifier / Beautifier

Free Online CSS Minifier & Beautifier

Minify CSS to reduce file size for production, or beautify minified CSS to make it readable again. See exactly how many bytes you save with the built-in size comparison.

What Does Minify Do?

Minification removes unnecessary whitespace, comments, and redundant semicolons from your CSS without changing its behavior. This reduces file size and improves page load times.

What Does Beautify Do?

Beautification takes compressed or minified CSS and formats it with proper indentation, line breaks, and spacing — making it easy to read and edit.
