Free CSS Formatter & Beautifier

What Is CSS Formatting?
CSS formatting (beautification) adds proper indentation and line breaks to make your code more readable. Minification does the opposite—removing whitespace to reduce file size. Both versions have identical rendering behavior; the difference is purely for readability (beautified) or file size (minified).

Frequently Asked Questions
What is CSS beautification?
CSS beautification reformats your code to be more readable by adding proper indentation and line breaks. It's the opposite of minification and makes debugging much easier.
When should I use minified CSS?
Minified CSS removes all whitespace and is best for production to reduce file size and bandwidth. Use beautified CSS during development for easier debugging. Many build tools automatically minify when you deploy.
What does 'sort properties alphabetically' do?
This option alphabetizes CSS properties within each rule (e.g., border before color before display). Some developers prefer this for easier scanning, though it doesn't affect how CSS renders.
