Formats for more space for pictures and videos: HEIF and HEVC explained

Everyone knows JPEG. This image format is recognized by all programs and apps that can display images as well as by web services and web pages and can be passed on from one device to another without any problems. But what is HEIF? Also an image format, but more modern and efficient than JPEG. Since iPhone 7 and iOS 11, this format can be used by the camera to save the photos, as well as on the more recent iPads. The Mac has been able to handle the image format since macOS High Sierra. Communication problems can occur with other operating systems and on the web.
