WEBP converted picture almost 3 times bigger than JPG on desktop view

WebP images should never be 3x bigger with equal quality settings. There's something seriously wrong somewhere. Maybe it tries to store them as "lossless"? Or something like that.

(at rokka, we actually don't check webp vs jpeg, because webp is never much bigger than jpeg. And in almost all cases smaller, so it's not worth the effort, we do that for avif vs webp, though)

I had the same problem, the size was always bigger in webp than jpeg.
It appeared that the quality in the filter is not taken into account for the webp.
I don't know how to configure this for one filter but you can configure it globally like :

liip_imagine:
    driver: "gd"
    default_filter_set_settings:
        format: webp
    webp:
        generate:    true
        quality:     80

It will be the exact same size as jpeg for the same quality so I don't know if it worth it except avoiding google lighthouse saying "hey try webp it's better".

this bundle is not doing any image conversions on its own. your best chance is to ask at the actual image library that you use (gd or imagick).

i think with https://rokka.io/ we also have logic to check if webp actually is better than jpg and discard webp if it does not pan out. maybe @chregu has some input on that. (but this is only as inspiration for you to add on top of it, such logic would be out of scope for the liip imagine bundle)

@ajaysSymfonyExpert i close this issue as the problem seems to be with the image converter and not the symfony bundle. but feel free to comment if you found the issue, for future reference if others run into a similar problem.
