Minifying HTML, CSS and JavaScript files means stripping all dispensable parts from their code.

For example, the source code from a CSS file might look like this:

After minifying it, the same code looks like this:

As you can see, minification removes unnecessary elements like comments, line breaks or whitespace. They’re unnecessary because they don’t contribute to anything on the page.

These elements help developers write and review code, but they slow browsers down because they enlarge your website’s files. The larger the files, the more work a browser has to do to download and parse them.

By removing these elements, NitroPack makes your website’s code files lighter without affecting the design or functionality.
