CSS Formatter & Minifier
Beautify or minify CSS with configurable indentation and size comparison.
Frequently Asked Questions
What does CSS formatting do?
CSS formatting (beautifying) takes minified or poorly indented CSS and re-formats it with consistent indentation, one property per line, and proper spacing around selectors and braces. This makes stylesheets much easier to read, maintain, and debug.
What is CSS minification?
CSS minification removes all unnecessary whitespace, comments, line breaks, and trailing semicolons from CSS code. This reduces file size for faster page loads in production, while preserving the exact same styling behavior.
Does this tool modify my CSS rules?
No. Both formatting and minification preserve your CSS rules, selectors, properties, and values exactly as written. Only the whitespace and comments are changed — your styles will render identically in the browser.
What indent style should I use?
Two spaces is the most common convention in web development. Four spaces is sometimes used in larger projects. Tabs allow each developer to set their preferred visual width. Choose what matches your team's style guide.
How much can CSS minification reduce file size?
Typically CSS minification reduces file size by 15-40%, depending on how much whitespace and comments are in the original. Combined with gzip compression on the server, the savings can be even more significant for production deployments.
