What is minification and when is it required?
The term’minify’ refers to a technique for reducing the amount of your website’s files. It does this by deleting extraneous characters, lines, and white spaces from the original code.
Here’s an example of standard CSS:
The code will look like this once it has been minified:
You may also minify PHP scripts, however, this will have no effect on page load speed for your visitors. PHP is a server-side programming language, which means it operates on servers before anything is transmitted to the visitor’s web browser.
The benefit of minifying files is that they load quicker, which improves WordPress speed and performance.
However, other experts argue that the performance gain for most websites is insignificant and not worth the effort. On most WordPress sites, minification merely reduces a few kilobytes of material. By optimizing pictures for the web, you may minimize the time it takes for a website to load.
This technique is simpler and should be used by all users. It works no matter which WordPress hosting service you choose.
