HEIC
High Efficiency Image Container
HEIC is a file extension that Apple uses for the HEIF image format, which are usually coded by HEVC codec (High Efficiency Video Compression). This format is great for Live Photos because it can contain an image sequence. The best part about it is that you can store twice as many pictures in the HEIC format as in JPEG in the same size and quality because it uses the next-generation file compression.
