The Basics of Data Compression on the Web

Data compression on the web is the process of reducing the size of data transmitted by websites. Depending on the data type—text, images, stylesheets, scripts, fonts—there are various ways to go about compressing data.

The main components of a webpage

For instance, minification of HTML, CSS, and JavaScript is a simple way to reduce the amount of data sent by browsers. Here, the minifier compresses the text by removing unnecessary characters such as comments and whitespaces from the source code.

In the example below of a simple HTML document, there are three content types: HTML markup, CSS styles, and JavaScript code.

Each content type has unique syntax and semantics. Overall, this HTML document has 357 characters in total.

    /* kinsta-banner is used on the homepage only */
    .kinsta-banner { font-size: 150% }
    .kinsta-banner { width: 75% }
    <!-- kinsta banner START -->
    <!-- kinsta banner END -->
    kinstaScripts(); // random scripts used on the page

The above code is easy to read and follow. It’s ideal for development. However, it’s unnecessary for the browser to read comments and have perfectly indented tags. A smart compressor can analyze this document and remove all the unnecessary bits from it.
