We show pictures on our homepage which contain several parameters in the file name. According to my clarifications, Cloudflare checks the extension and if it is != .jpg, for example, the image is not cached and can therefore not be converted into a WebP format.
Therefore we have set a last parameter at the end with &format=.jpg. This causes the image to be cached, but the image is still not converted into a WebP format.
Example 1 (good)
4banner_big.jpg 200 webp (Index)
Example 2 (not good)
banner2a9.jpg?context=bWFzdGVyfHJvb3R8MzI3Nzl8aW1h…jY5MmIyNzFlM2U2NTQzNTM3MDNiNGU1OTlkNg&format=.jpg 200 jpeg (Index)
Is there any way to convert images to WebP format with additional parameters?
