Minify CSS Online Tool: How to Use It

This minify css online tool takes only a few steps:

1. Paste your CSS into the input box.
2. Press Minify to compress the code.
3. Check the result and the amount of space saved.
4. Press Copy and paste the minified code into your stylesheet or theme.

Here is a small example of what happens to your code:

/* Button style */
.btn {
  color: #ffffff;
  background: #2563eb;
  padding: 10px 20px;
}

After minifying, the same rule becomes:

.btn{color:#fff;background:#2563eb;padding:10px 20px}

Add a custom site icon from our Favicon Generator to finish your site's polished, fast-loading look.

Tips for better CSS performance

• Keep an unminified copy of your CSS for editing, and publish only the minified version.
• Remove unused rules before minifying for the biggest size savings.
• Combine small stylesheets into one file to reduce page requests.
• Test your page after replacing the stylesheet to make sure everything looks right.
