FAQ
What does CSS minification do?
CSS minification removes comments, whitespace, newlines, and redundant semicolons — anything that's not needed for the browser to parse the stylesheet. This reduces file size and improves page load speed.
How much can CSS be minified?
Typically 20–40% for well-written stylesheets. CSS with lots of comments, blank lines, or developer-friendly formatting can achieve 50%+ reduction.
What is CSS beautification?
Beautification (or pretty-printing) takes minified CSS and adds proper indentation, newlines, and spacing to make it easy to read and edit.
Does minification change how CSS works?
No. Minification only removes whitespace and comments that are invisible to the browser's CSS parser. The computed styles remain identical.
Is my CSS data safe?
Yes. All processing runs in your browser using JavaScript. Your CSS never leaves your device and is never sent to any server.
