The HEIF format, short for High Efficiency Image File Format, is a modern file format designed for storing images and image sequences. It functions as a so-called "container," meaning that it can store multiple different types of data within a single file, such as several photos at once, animations, audio, or text. The main advantage over the older and more widespread JPEG format is more efficient compression, which is a method for reducing data size. Thanks to the use of the HEVC (High Efficiency Video Coding) compression standard, it can create a file that is approximately half the size of a JPEG while maintaining comparable visual quality. In addition to saving space, it also supports greater color depth, which allows for smoother color transitions. The format can also store transparency or image sequences, which are used for motion photos.
