JPG images are not displayed as converted in WEBP

Hi @juriix,

Thank you for your message.

From what I can see, only two images are not available in WebP format, and the rest are available in WebP format. The reason for this situation is the limitation of the WebP format. These images were probably previously optimized and after conversion to WebP they weigh no less than the original file, so the plugin uses the original files.

In this situation, I recommend you to try the AVIF format on your website. I did an analysis to learn more about the potential benefits of using the AVIF format for you. Images converted to the AVIF format on your website will weigh 36% less than images converted to WebP only, maintaining even better image quality. Then images such as ROM-580×400-1.jpg will weigh less than the originals and will be loaded in the next-generation format.

In addition, please remember to purge the cache in your hosting panel. This should be the first step.

Best,
Mateusz

Other images are imported as WebP earlier.
Images modified with the plugin will only show up as I showed and only in the administration, but not on the frontend.

@juriix How were they previously imported as WebP?

From the import feed where they were already in webp see https://www.kudyznudy.cz/aktivity/koupaci-biotop-lhotka or what I manually converted to webp before inserting.
I deleted the web, imported the products using wp all import and there is only JPG. What is WEBP so I have indicated modified earlier, manually.

@juriix In the first post you provided a different website URL, now you are sending a different one. On this website images are loaded from a CDN server.

I am sorry, but I do not quite understand what you expect from me. Please tell me how can I help you?

You asked me how come I already have images in WEBP and so I wrote to you that I download images from for example https://www.kudyznudy.cz/aktivity/koupaci-biotop-lhotka who already have WEBP and I edited some of jpg manually. Unfortunately not all image suppliers have images in WEBP so I need to convert them.
From you I want, I need to know why WEBP does NOT appear on the frontend which as I sent screenshots is processed even if I upload the image manually not just via wp all import.
First link -> The page I need help with.

@juriix On this page images are loaded from the CDN server cdn.kudyznudy.cz, so my plugin cannot handle them. Please start by deactivating the CDN service.

The link was just for an example of where webp has already https://www.kudyznudy.cz/aktivity/koupaci-biotop-lhotka, forget it.
It doesn’t matter where the image is from if it’s via Wp all import or uploaded manually, the images don’t work as WEBP. When I look in the media it pretends to be processed so I’ve sent screenshots but they don’t show up on the frontend.

I can send you the approaches and you can try.
