An HEIC file is a High-Efficiency Container Image file format that can store multiple images as a collection in a single file. The format was adopted by Apple as variant of the HEIF with the launch of iOS 11. It was adopted as the default file format for storing images in compressed form on mobile devices. HEIC, like HEIF, are compressed using the High Efficiency Video Coding (HEVC) standard and are smaller in size without compromising the quality.
HEIC File Format
HEIC is based on the HEIF file format and uses the HEVC standard (also known as H.265) for achieving compact file size without compromising quality. When an image is taken on iOS device (such as IPhone, IPad, or MacOS), it is stored as HEIC file to these devices. HEIC is a container format that can store single or multiple images along with meta data that describes each image. One such example of metadata is EXIF that includes the tagging and metadata information with the image file.
