Compress / Minify your CSS
Minifying CSS takes the beautified and well formed CSS code that you have written and removes the spacing, indentation, new lines and comments. These elements are not required for CSS to be used. It also makes the CSS more heavy to read.
The purpose of minifcation of CSS is to increase the speed of a website. Minimisation can make a CSS up to 20% smaller, resulting in a faster load time.

FAQs
Q.: What is CSS Minification?
A.: CSS Minification is the process of removing unnecessary characters from your style sheets—such as white spaces, new lines, comments, and block delimiters—without changing the functionality of the code. This results in a smaller file size, which helps your website load faster by reducing the amount of data the browser needs to download.
Q.: How does minifying CSS improve web performance?
A.: Minifying your CSS directly improves the First Contentful Paint (FCP) and Largest Contentful Paint (LCP) metrics. Smaller CSS files lead to faster browser parsing times and reduced network latency. When combined with Gzip or Brotli compression, minified CSS can reduce payload sizes by up to 80%.
Q.: Will minifying my CSS break my website layout?
A.: No. A professional CSS Minifier like the one on The Udit Kumar only removes "non-operational" characters. The logic, selectors, and properties of your CSS remain exactly the same. It is a standard industry practice used by major frameworks like Bootstrap, Tailwind, and React.
Q.: What is the difference between Minification and Compression?
A.: Minification happens at the code level (removing spaces and comments), while Compression (like Gzip) happens at the server level (using algorithms to shrink data for transmission). For the best performance, you should always minify your CSS first and then enable server-side compression.
Q.: Should I keep a copy of my unminified CSS?
A.: Yes. Minified CSS is not human-readable. You should always maintain your original, "pretty-printed" CSS files for development and editing. Use our tool to generate the .min.css version only when you are ready to deploy your website to a live server.
