See the Difference: Before and After

Here is a simple example of what minification does. The original code:

<!-- Main heading -->
<div class="box">
    <h1>Hello World</h1>
    <p>Welcome to my site.</p>
</div>

And the minified result:

<div class="box"><h1>Hello World</h1><p>Welcome to my site.</p></div>

The page looks identical in the browser but the file is smaller. Once your page is lean, add a custom site icon with our Favicon Generator for a more polished look.
