Wordpress LScache Plugin: Images Optimised, but GTMetrix still saying they arent optimised
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hey, I have gone through and optimised all the images of a site I am working on, using your LiiteSpeed Cache plugin. The image optimisation process went through smoothly, but when I go and get GTMetrix to have a look at the site, it comes back telling me that the images arent optimised (it gives an Image Optimised score of 0). See here: https://gtmetrix.com/reports/welcomecottage.com.au/hsxZZyVc Any idea why GTMetrix is saying they arent optimised? Should I be doing something else? Thanks. The page I need help with: https://welcomecottage.com.au Hi higgalls, First, we need you help to verify that all images are being optimized, e.g. https://welcomecottage.com.au/wp-content/uploads/2018/03/DSC_1847.jpg. From admin: Check Media->Library, all images displays with LiteSpeed Optimization : Original saved xx%? From ssh: ll wp-content/uploads/2018/03/ | grep DSC_1847 Please let us know the result, thanks. Best, Eric Hey, Yep, in the media library they are all saying they are optimised. When I look up the one you suggested (DSC_1847.jpg), in the media library it says: WebP saved 173.74K Original saved 1007B The amount that the original saved varies quite a bit, but there are a LOT which only saved in a magnitude of up to 1 or 2KB (and many, like in the example above, around the 1000B area), whereas the WebP option seems to save a significant amount more. However, they are all saying they are optimised (there are a couple that only have the WebP saving listed ? I am assuming because they were already optimised and no further savings could be made to the normal .jpg file). Now, in the GTMetrix report I shared with you, I hadnt enabled the Image WebP Replacement option in the settings. Should I be doing that? However, even when I do enable that option, and then clear cache, I still have the same issue where GTMetrix gives a 0 (F) rating for Optimise Images. At Pingdom, it is showing that it is using the optimised WebP images when I have that setting enabled. So could it be that GTMetrix simply doesnt support WebP? But even if it doesnt, the images are still optimised and so it should be reporting that. Hope that all makes sense. Anything else I can do? Or should I use a different image optimisation plugin? Also, is there a plugin you recommend to resize images? Because I dont think it can be done in your plugin to set max width etc. Thanks. I have manually gone through and resized several of the images on the front page, which has increased the optimised rating, but it is still saying that there are images needing to be optimised (which have been optimised with LiteSpeed Cache) Hi higgalls, Thanks for your information and help. Our cache plugin developer noticed and will keep improving Image Optimize in the future days. Best
