CSS Minifier and Compressor Online 2025

We improve and update our CSS compression tool weekly to achieve the highest possible results. The current version is 1.03.

What are the benefits of CSS code compression or minification?

The most important benefit is faster website page loading. Proper CSS minification is critical for speed improvement, especially when accessing sites from mobile devices. Another, no less important meaning is the size of the place occupied.

How to use this tool?

1. In the first field, paste or type in your CSS code that you want to compress.

2. A "Compress CSS" button will appear below; click it.

3. If your CSS code is correct, the second field will contain the ready-to-use code for your applications.

4. Two methods will be available for you to copy the ready-to-use code:

The first, and most convenient, method is by clicking the additional button labeled "Copy Compressed CSS". Your code will then be copied to the clipboard, allowing you to easily paste it where needed.

The second method is suitable for those who need partial copying: you can simply select the desired fragment from the second field and copy it in the standard way.

5. Copying Safety.

We have taken care to protect the ready-to-use code from accidental changes during copying, so you no longer need to worry about this.

6. What do the errors mean?

Typically, error messages appear when the tool detects incorrect CSS code. It specifies the line where the error was found and provides a description of the error itself, which greatly facilitates the correction of your code.
