How to Disable Jetpack’s CSS Concatenation on WordPress

Jetpack, a plugin by Automattic, is a popular all-in-one solution for adding extra functionality to a WordPress site. In this post, we’ll discuss how to disable Jetpack’s CSS concatenation on WordPress.

To disable Jetpack’s CSS concatenation, you can use the following code snippet:

This code uses the add_filter function to add a filter to the jetpack_implode_frontend_css hook. The __return_false function is used as the callback function, which simply returns false. By returning false, Jetpack will be prevented from concatenating the frontend CSS files. The third argument, 99, is the priority of the filter. By setting a high priority of 99, the filter is applied after any other filters that may be attached to the same hook.


Disabling Jetpack’s CSS concatenation is a simple process that can be accomplished by adding a single line of code to your WordPress site. Whether you’re a developer or a site owner, this post will help you get started with disabling Jetpack’s CSS concatenation and improving the performance of your WordPress site.
