Hi, The brighter webp icon means the main image has webp file , the dimmer one means the main image doesnt have webp file. from the origin optimization percentage (like only 2/3%), I assume your images were already pretty much optimized before LSCWP. In some case, particularly if webp is bigger than original , it will not save it, please reset it and try again and see if you can get webp , if not , its mostly like the reason. Best regards, Hi @CacheCrawler, thanks for answer. Yes, it was error. But some images has webp format, some dont has. What it can be? Hi, Thats what I mentioned , depends on each individual images, some times , the webp file will be bigger than origin , so it will not save it. Thats why I suggested try reset it for once and re-optimize and see if you can get it. In rare case, an external error might cause some image failed to webp , but if you do it twice or thrice , and still cant get it , its most likely the webp-bigger-than-origin case. Best regards,
