Wordpress LScache Plugin: Need Help WIth Generating Webp Images using LSCache
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hi, I have a website which is running WordPress v6.0 with LSCache v4.6 and OpenLiteSpeed Server. Initially when I optimized the entire media library of images, I turned the Create WebP Versions to Off and Image WebP Replacement to Off. Then I used LSCache to optimize the images which generated only JPGs. I now want the WebP version of the images as well. I turned the Create WebP Versions to On Image WebP Replacement to On and saved the settings. My question is how do I make LSCache generate the WebP images. Do I have to purge all the optimization and restart the process again to get both the JPGs and the Webp Formats. I need advice on how to proceed as our library has over 10000 images. Regards, Sainik. you will need to destroy all optimized data and re-start it from beginning Hi @CacheCrawler Thank you so much. I had one additional question I wanted to ask. I have the following Image Thumbnail Group Sizes listed et-pb-post-main-image ( 400px x 250px ) et-pb-post-main-image-fullwidth ( 1080px x 675px ) et-pb-portfolio-image ( 400px x 284px ) et-pb-portfolio-module-image ( 510px x 382px ) et-pb-portfolio-image-single ( 1080px x 9999px ) et-pb-gallery-module-image-portrait ( 400px x 516px ) et-pb-post-main-image-fullwidth-large ( 2880px x 1800px ) et-pb-image?responsive?desktop ( 1280px x 720px ) et-pb-image?responsive?tablet ( 980px x 551px ) et-pb-image?responsive?phone ( 480px x 270px )` Of the ones listed, I do not require the following et-pb-portfolio-image ( 400px x 284px ) et-pb-portfolio-module-image ( 510px x 382px ) et-pb-portfolio-image-single ( 1080px x 9999px ) Does de-regsitering the following sizes, reduce the number of image groups that is submitted to LSCache, and in effect reduce the disk space? yes , LSCWP will try to optimize whatever images it sees in database Thank you for answering my questions @CacheCrawler
