CSS Minifier

Compress your CSS code by removing unnecessary whitespace, comments, and formatting.

How to Use CSS Minifier?

  1. Paste CSS: Copy your stylesheet content into the "CSS Input" box.
  2. Minify: Click the "Minify CSS" button to start compression.
  3. Check Savings: See exactly how much space you saved in the stats panel.
  4. Copy & Use: Copy the minified code and replace your original CSS file content.

Performance Tip

Always keep a copy of your original, readable CSS file (e.g., style.css) for editing, and serve the minified version (e.g., style.min.css) to your users.

Frequently Asked Questions

No. Minification only removes characters that browsers don't need, like comments, newlines, and extra spaces. The logic and styling rules remain exactly the same.
It varies, but typically you can expect to reduce file size by 15-30%. This can significantly improve page load speeds, especially on mobile networks.
You can use a "Beautifier" or "Formatter" tool to make the code readable again by adding indentation, but comments and original variable names (in JS) cannot be recovered if they were removed.
