Wordpress LScache Plugin: Webp image problem
Last Updated on: Wed, 15 Apr 2026 00:00:02 Hello, I a m using this nice plugin and I have a problem, as you can see : https://developers.google.com/speed/pagespeed/insights/?hl=fr&url=https%3A%2F%2Fwww.docteur-fitness.com%2F I have 4 images that havent webp extension. I dont know why.. can someone help me ? Thanks you Hi, https://www.docteur-fitness.com/wp-content/uploads/2020/03/alimentation-diabete-320?240.jpg.webp because some of them doesnt have wbep replacement , so it will fallback to .jpg Best regards, @CacheCrawler thank you for your response. How do I get these images to have a webp version? Isnt it the plugin that does it automatically? For the other images it is done by itself. Can we do it manually if not? In my FTP, I have alimentation-diabete-320?180.jpg.tmp what does it mean ?? ^^ @espacemusculation if taking one of the example images such as https://www.docteur-fitness.com/wp-content/uploads/2020/03/etude-vetement-compression-musculation-1160?653.jpg This converted to webp will in fact be larger than the jpg version of it. To be smaller as a webp image, the quality would have to be set to roughly 68 (out of 100) to be smaller. The ?conomies potentielles that Pagespeed Insights list are purely estimations (a simple math formula), its not what theyre actually able to get it to. Using a quality of 68 would simply make the image look really bad. Thank you for your explanations @lucasrolff what is the extension . tmp ? I just saw that all the images have this extension instead of .webp. can I replace manually via FTP .jpg version to .webp version ? 97,5 for jpg and 97,1 for webp with https://convertio.co/ The only thing I can see in the code, would be when it fetches the images from the image optimization servers, if the checksum for comparing the image (if its intact) would be a mismatch , then it seems the .tmp files can be left over. That would however, give a message of Pulled image md5 dismatched in the admin panel from what I can see. Thanks you very much @lucasrolff what do you think about Lossless ? 516 vs 56 ko @lucasrolff what do you think about Lossless ? 516 vs 56 ko
