Minification

Minification is a technical process that removes unnecessary characters from website code without changing how it works. By eliminating white space, line breaks, and comments, and shortening variable names in your CSS, HTML, and JavaScript files, minification reduces file sizes. Smaller files mean faster loading times and less bandwidth use, creating a better experience for your website visitors.
