Half at Mac App Store analyse

Half the size of your movies and videos, without sacrificing quality. Half uses state-of-the art compression techniques to drastically reduce the size of your videos without any perceptual loss of quality. Save up to 2x the storage and send or download your media twice as fast. On average, Half reduces file sizes by ½. For some videos, those that have already been highly compressed or are of low resolution, it wont have such a great effect. For typical videos, especially for 4K videos such as those shot on an iPhone, it tends to give an even better savings. Half uses HEVC, also known as h.265, a modern compression codec, supported on all macOS 10.13 and iOS 11 devices.
