Minify and compress your CSS Код instantly. Remove whitespace, comments, and unnecessary символов for faster page loads. 100% на стороне клиента.
CSS Minifier is a free online tool that compresses your CSS code by removing unnecessary whitespace, comments, and redundant characters. Smaller CSS files mean faster page loads, reduced bandwidth usage, and better overall website performance. All processing happens entirely in your browser — your CSS code never leaves your device.
Yes! Minified CSS is functionally identical to the original. Only unnecessary characters like whitespace, comments, and redundant syntax are removed. All CSS selectors, properties, and values remain intact and will render exactly the same in any browser.
No, CSS minification is completely safe. It only removes non-essential characters that do not affect rendering. Your styles will look and behave exactly the same in the browser after minification.
Typically you can expect 15–40% size reduction depending on how much whitespace and comments your CSS contains. Well-commented CSS with lots of indentation can see even higher savings. Our tool shows you the exact percentage saved in real time.
Yes! Use our CSS Formatter tool to beautify minified CSS back into a readable format with proper indentation and line breaks. This is useful when you need to edit or debug previously minified code.
No. All processing happens entirely in your browser using JavaScript. Your CSS code is never sent to any server or stored anywhere, ensuring complete privacy and security.
This tool minifies plain CSS only. For SCSS, Sass, or Less, you should first compile to CSS using their respective compilers, then use this tool to minify the resulting CSS output.
Yes, CSS custom properties (variables) are fully preserved during minification. The tool safely handles var(--property) references and does not alter their functionality.
Minification removes unnecessary characters from the source code (whitespace, comments, redundant syntax). Compression (like Gzip or Brotli) further reduces file size at the network level. For best results, use both: minify your CSS first, then enable Gzip/Brotli on your server.
