CSS Minifier

Minify CSS Online – Free CSS Minifier Tool

This CSS Minifier tool helps reduce your CSS file size by removing unnecessary spaces, line breaks, and comments. Minified CSS loads faster, improves website performance, and is easier to deploy in production environments.

Why Minify CSS?

CSS files are often written with extra formatting to help developers read and edit them easily. However, browsers don’t need those extra spaces or line breaks. Minifying CSS offers several benefits:

• Improve website load speed
• Reduce file size and bandwidth usage
• Enhance performance, especially for mobile users
• Obfuscate code slightly to make it less readable

How to Use the CSS Minifier

1. Paste your CSS code in the input field
2. Click the "Minify" button
3. Copy the compressed CSS and use it in your project

Example

Before:

body {
  margin: 0;
  padding: 0;
  font-family: sans-serif;
}

After:

body{margin:0;padding:0;font-family:sans-serif}
