Compressing the images and graphics on your website makes your website load faster for all visitors, in turn this increases your search rankings – it really is a win-win situation. Our LiteSpeed Cache plugin can do this for you, for free.
Assuming you’ve already followed the guide to installing the plugin, login to your WordPress admin interface, hover over the ‘LiteSpeed Cache’ menu and click ‘Image Optimisation’.
Then click to initialise optimisation.
This will complete and you’ll be redirected to the interface.
Click to send your first optimisation request. The first batch of your images are then sent to the server, and it gets to work on them. When they are ready, it sends a notification back to your website so that it can automatically retrieve them. As you compress more images, your number of credits increases, allowing you to compress more at a time. You may need to revisit this page a number of times to submit all of your images.
The information to the right of the screen shows your progress and how much reduction has been achieved.
By visiting the ‘Media’ menu on your WordPress site, you can see the effect on each of your images.
As you can see, the changes are fairly significant and with a large number of images on your site will improve load times immensely.
You can increase the effect further by enabling WebP images. To do this, go to your LiteSpeed Cache settings menu, and select ‘Show Advanced Options’ then click on menu  Media. There are two options to enable – as shown below.
Once your credit limit has reached 1200 you can also enable automatic image compression in this menu, so any future images are compressed automatically, without needing to do anything.
