Using the LiteSpeed Cache Image Optimisation tool in WordPress
You'll need to have the WordPress LiteSpeed cache plugin installed to follow this guide. We also suggest you follow the advise in the WordPress optimisation guide to pre-optimise your images - ensure they are sized correctly and at a suitable resolution (dpi) before uploading and using them on your site.
The LiteSpeed Cache Image Optimisation tool converts your uploaded image files to the more efficient
.webp format. Within the LiteSpeed Cache > Advanced Options > Media tab you can then configure LiteSpeed to automatically serve these
.webp optimised images across your site.
LIteSpeed have produced two guides with a complete walk-through of the Image Optimisation Tool which we link to below.
The first walks through the use of the LiteSpeed Cache Image Optimisation tool - external link opens in a new window.
The second guide details the options and settings within the WordPress plugin LiteSpeed Cache > Advanced Settings > Media tab including how to have images auto-optimised and auto-replaced with the optimised
.webp versions. LiteSpeed media configuration - external link opens in a new window.
