FAQ

Jetpack Boost makes small changes to the way that data is sent from your WordPress site to your users’ browser, to enable the browser to display your site faster.

Jetpack Boost includes a growing number of separate features which can be turned on individually to improve your site’s performance. These include:

Optimize CSS Loading: This feature determines the most important CSS that your site needs to display your site’s initial content as quickly as possible, and embeds it directly into your site header.
Page Cache: This feature stores your website’s pages as static HTML files, bypassing the need for dynamic generation. This means visitors receive pages faster, reducing wait times and improving overall site performance.
Defer Non-Essential JavaScript: This feature forces all of the JavaScript which is not deemed essential to displaying your site to load after your site’s main content has been loaded.
Image CDN: This feature automatically resizes images to a more appropriate size for your visitors’ screens, converts them to modern image formats, and serves them from Jetpack’s worldwide network of servers.
Concatenate JS: This feature reduces the size of your JavaScript resources, and automatically combines them into fewer files, allowing your site to load faster with fewer requests.
Concatenate CSS: As with concatenating JavaScript, this feature shrinks your CSS files and allows them to load with fewer requests.
