Could you consider supporting mozjpeg?

MozJPEG improves JPEG compression efficiency achieving higher visual quality and smaller file sizes at the same time. It is compatible with the JPEG standard, and the vast majority of the world's deployed JPEG decoders.

Thank you very much for your suggestion. I will check if it's possible to integrate mozjpeg to ImageMagick as Converseen uses IM to manipulate images.

It should be easy because mozjpeg is simply a fork of libjpeg-turbo (which you already use) with a bunch of tweaks and tuning but without changing the name or the way it works. It's an exact drop-in replacement.
