Convert MIX to JPEG

It seems that the only mix to jpeg conversion is related to export of old Microsoft PhotoDraw images (.mix) to JPEG format (.jpg, .jpeg), something that would most likely require a dedicated graphics convert. You can also try some of the popular picture viewers with broad format support, such as XnView. These programs might unfortunately not always offer direct export to JPEG in this particular case, but perhaps offers export to other format which can then be saved as JPEG file with another conversion.
