Half uses state-of-the art compression when available to drastically reduce the size of your media.
On average, Half can reduce photo file sizes by ½. For typical photos, especially for screenshots and PNGs, it tends to give an even better savings. For videos, it works best on those of higher resolution such as 4K.
Half uses High Efficiency Image Format (HEIF/HEIC) and High Efficiency Video Compression (HEVC), modern compression codecs.
