HEIF (High Efficiency Image File Format)

The HEIF is a modern image format, with the final specification completed in 2015. The format is a container format, which, while mostly used for storing image data, can actually support video, audio, and text data streams.

HEIF files are binary in nature and offer an alternative to existing digital photo formats such as JPEG features better compression while retaining comparable image quality. In some cases, the file size can be 50% that of the equivalent JPG file.
