FAQ
Minification removes comments, extra whitespace, and unnecessary characters from CSS without changing how it works. The result is a smaller file that loads faster — often 20–40% smaller than the original.
Yes. Minified CSS is fully valid — browsers parse it identically to formatted CSS. The only difference is that whitespace and comments are removed, which browsers ignore anyway.
Typical savings are 20–40% for hand-written CSS. Heavily commented or indented stylesheets can shrink by 50% or more. The savings counter shows you the exact reduction for your file.
Use Beautify when you receive a minified CSS file and need to read or edit it. It adds consistent indentation and line breaks, making the code human-readable again.
