CSS Minifier / Beautifier

Minify and beautify CSS online. Free CSS minifier and formatter tool for developers.

What is CSS Minifier?

CSS Minifier removes unnecessary characters from your CSS code, such as comments, extra whitespace, and redundant semicolons, to reduce file size and improve page load speed. The beautifier does the opposite: it formats compressed CSS into a readable, well-indented structure for easier editing and debugging. Both operations run entirely in your browser with no data sent to any server.
