This CSS minifier tool simplifies CSS (Cascading Style Sheets) source code by condensing it into a compact, minified version. By eliminating unnecessary characters like whitespace, comments, line breaks, and formatting indents, it significantly reduces the size of the CSS code without altering its functionality.

What is CSS Minifier?

CSS Minifier is a free online tool that compresses and minimizes CSS code. CSS, or Cascading Style Sheets, is crucial for defining the visual aspects of HTML in web browsers, including colors, sizes, fonts, and more. There are three types of CSS: inline, internal, and external. Inline CSS is directly written within HTML tags, while internal CSS is enclosed within <style> </style> tags in HTML documents. External CSS is stored in separate .css files and linked to HTML via <link> tags.

Minifying CSS files reduces their size, leading to faster page load times and improved performance. This optimization is particularly beneficial for enhancing user experience by reducing the time it takes for content to appear on screen. Using minified or compressed CSS versions is recommended for webpages to optimize performance effectively.

Here, you can see how CSS code looks before and after minification process.
