Starting with iOS 11, Apple moved to HEIC (High Efficiency Image Coding) image format on the iPhone. The biggest advantage of HEIC is the ability to store images at half the file size of JPEG with no discernible difference in image quality. But there is a catch though. Even after two years of adoption, HEIC’s cross-platform availability is still a hit and miss. We have seen reports of students failing in AP exams due to the website’s lack of support for HEIC image format.
