Frequently Asked Questions

What does CSS minification do?▾

CSS minification removes all unnecessary characters from your CSS code — comments, whitespace, newlines, and redundant semicolons — without changing functionality. This reduces file size, which means faster downloads and improved page load times.

What does CSS beautification do?▾

CSS beautification (or prettification) takes compressed or minified CSS and reformats it with proper indentation, line breaks, and spacing. This makes the code readable and easier to debug or edit.

How much file size can minification save?▾

Typical savings range from 15% to 40% depending on how much whitespace and comments your original CSS contains. The tool shows you the exact original size, minified size, and percentage saved.

Does minification change how my CSS works?▾

No. Minification only removes formatting characters that browsers ignore anyway. Your styles, selectors, properties, and values remain exactly the same.

Is this tool free?▾

Yes, completely free with no signup required. All processing happens in your browser — your CSS code is never sent to any server.
