HEIF (High Efficiency Image File format) is a file format for storing digital images and image sequences. Its companion file format, HEIC, can encapsulate multiple copies of HEIF sequence data, and additional non-photographic media. HEIF and HEIC files are created by the camera applications of modern Android and iPhone devices, and by professional grade digital cameras. The file format was developed by the Motion Picture Experts Group, and has been used commercially since 2015.
Advantages of HEIF
HEIF offers more efficient compression than the JPEG file format. On average, HEIF can retain 100% additional quality and detail compared to a JPEG file of similar file size. In addition, HEIF can be used to capture burst photography, in which many photos are captured in rapid sequence, in a single file.
HEIC is a "container" format that can package multiple HEIF image sequences with additional media such as audio recordings. Examples of applications which use the HEIC container format include the Live Video feature of iOS.

HEIF and HEIC files have the file extensions .heif and .heic. When specified in a program or web page, their Internet Media/content types are:
