Wordpress LScache Plugin: Compatibility for wp-rocket
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi, Since I am not on Litespeed Web server, I use another caching plugin (Wp Rocket) alongside Litespeed Cache. I decided to use Image optimization section of Litespeed to serve Webp images to Chrome and Opera. Is it doable? Do you get along with WP Rocket? And Would WP Rocket cache the webp images LSC produced? Hi auludag, Guess as long as you dont have/use any other image optimize plugin, LiteSpeed Cache imgae optimization work should be good. After optimizing, you can still convert all back to normal if you dont want it. Best, removed, since Eric already replied Thanks @eric780217 Would WP-Rocket cache the Webp images that LSC produced? No, it wouldnt, but thats because, like LSCache, WP-Rocket doesnt actually cache images at all. It caches dynamic PHP, but it doesnt cache any static resources like images, CSS, or JavaScript. My earlier reply was probably not very helpful, so let me elaborate LSCache and WP-Rocket dont cache images, but they do generate the HTML that is then served from the cache, and they need to be able to include proper links to the WebP images within that HTML. So the real question is, if you use LSCache to generate the WebP, and turn Image WebP Replacement ON in the LSCache Media settings tab, will WP-Rockets generated HTML properly include the WebP modifications made by LSCache? This is something that needs to be tested, but we think probably it wont work. A google search shows that WP-Rocket may be working on adding WebP support, and if that is so, and if they look for WebP files in the same location as LSCache saves them, then you should be able to use LSCache for the optimization, and WP-Rocket to generate the HTML that displays them. I hope that made sense to you! Please let me know if it was unclear. hi @lclarke, I appreciate the time and effort you take, to explain to me. and thanks correcting the question. yes the correct question would be, will WP-Rockets generated HTML properly include the WebP modifications made by LSCache? Yes in their roadmap Webp cache appears. They will implement 3.2 You can see their roadmap from here: https://trello.com/b/CrUcz6Jy/wp-rocket-roadmap There is a catch it seems -from your words: if they look for WebP files in the same location as LSCache saves them :). Well I will share this message of yours at Trello forum, so someone from WP Rocket would read. Glad I could help And just so you know, if /uploads/2018/06/image.jpg is optimized by LiteSpeed, the WebP is stored in /uploads/2018/06/image.jpg.webp. Good luck!
