Paste your CSS below to minify it instantly. Removes comments, whitespace and unnecessary characters to reduce file size.
CSS minification is the process of removing all unnecessary characters from CSS code without changing how it works. This includes whitespace, line breaks, comments, and sometimes shortening color values and removing redundant semicolons. The result is a smaller file that loads faster in the browser.
A typical CSS file can be reduced by 20 to 50 percent through minification. For large stylesheets this makes a real difference to page load time. Faster pages rank better on Google and give users a better experience.
This tool removes all comments, leading and trailing whitespace, unnecessary spaces around selectors and properties, multiple spaces collapsed to one, and blank lines. The resulting CSS is functionally identical to the original but takes up much less space.
Yes, always. Serving unminified CSS in production wastes bandwidth and slows down your pages. Most build tools like Webpack, Vite, and Parcel minify CSS automatically as part of the build process. If you are not using a build tool, minify manually before uploading to your server.
Yes. Minification only removes characters that browsers ignore anyway - whitespace and comments. The actual CSS rules, selectors, and values are untouched. Your styles will look and behave identically after minification.
It depends on how much whitespace and how many comments your original CSS has. Typical savings are between 20 and 50 percent. Heavily commented CSS with lots of blank lines can see even bigger reductions.
Not easily. Minified CSS is very hard to read. Always keep your original formatted CSS as your source file and minify it as part of your deployment process. Never edit the minified version directly.
Yes. Everything runs in your browser. Your CSS is never sent to any server.
