Free Online CSS Minifier Tool

What is CSS Minification?

CSS minification is the process of removing all unnecessary characters from CSS source code without changing its functionality. This includes removing comments, whitespace (spaces, tabs, newlines), and sometimes even shortening color codes or other values where possible. The goal is to reduce the file size of the CSS, which leads to faster download times for your website visitors and improved page load speed.
