So could GraphicConverter optionally support MozJPEG as a possible JPEG encoder?
And as some third party tests indicate the Mozilla engineers succeeded in this goal.The goal is to provide a production-quality JPEG encoder that improves compression while maintaining compatibility with the vast majority of deployed decoders.

It depends if you are using the reference libjpeg library or the improved MozJPEG encoder.
WebP seems to have about 10% better compression compared to libjpeg in most cases, except with 1500px images where the compression is about equal.
However, when compared to MozJPEG, WebP only performs better with small 500px images. With other image sizes the compression is equal or worse.
I think MozJPEG is the clear winner here with consistently about 10% better compression than libjpeg.
Since most of the time WebP is used alongside JPEG fallback, by using WebP you will essentially double your storage costs with little benefit.
So, in the end, I would recommend using WebP in only few cases. […]
