CSS Formatter & Minifier lets developers format, beautify and minify CSS directly in the browser. Paste CSS, choose an operation, and copy or download the result without sending your stylesheet to a server.
What is a CSS formatter?
A CSS formatter, also called a CSS beautifier, reorganizes compressed or hard-to-read CSS with indentation and line breaks so selectors, declarations and blocks are easier to inspect and edit.
What is CSS minification?
CSS minification removes unnecessary whitespace and comments and reduces formatting characters while preserving the stylesheet structure. Minified CSS is useful when preparing production assets for delivery.

Readable CSS is easier to debug and maintain, while minified CSS can reduce unnecessary characters in files delivered to browsers. Keeping both operations in one browser-based utility makes it convenient to switch between development and production-friendly representations of the same stylesheet.
