Minify and compress CSS, JavaScript, and HTML code to speed up your site.
Minification is the process of removing all unnecessary characters from a source code without changing its functionality. This includes removing whitespace, line breaks, and comments.
Minified files are smaller and therefore load much faster in your users' browsers. This is one of Google PageSpeed Insights' top recommendations for improving your website's technical SEO.
