Best WordPress Minification Plugins – Top 5

Are you looking for the best WordPress minification plugins? If you are, keep reading this article. Here, we will list some of the best and most popular minification plugins in the market you can try.

But first, let’s have a look at what minification is and what are the benefits of minifying WordPress files. Let’s have a look.

What is Minification?

As the name suggests, the minification technique removes all unnecessary gaps like additional spaces, white spaces, and line breaks from CSS, JavaScript, and HTML files. Removing such things will help the server read the files faster; hence, the website’s speed will increase.

This is a common and straightforward WordPress speed optimization hack most people use.

Remember that the minified file and original file are the same in content. But since we remove all the unnecessary things from the file, the overall file size will become smaller.

Let’s have a look at the benefits of minifying WordPress files like CSS, HTML, and JS.

Benefits of Minifying WordPress Files (CSS, HTML, and JavaScript)

Minification has two advantages.

  • Save server space
  • Boost the website’s performance

Let’s see both.

Saving storage space: Since minification removes the unnecessary things from the CSS, HTML, and JavaScript files, it reduces the file size. If we minify all the CSS, HTML, and JS files, we can save some of the storage space on our server. It won’t be much, but it depends on your website’s size.

Speeding up WordPress website: When you reduce the size of the files and remove every unwanted thing, the server can read the files faster than before. This will result in faster website speeds.

Now, you know the main advantages of minification. Next, let’s see the top minification plugins you can use.

This will ensure you won’t use more storage on the server just for minified files. On top of that, you can also customize a unique cache path for the plugin. By tweaking your website’s wp-config.php file, you can choose a public library for all the minified cache files.
