What is HEIC?
High Efficiency Image Container
.heic, .heif
HEIC is a HEIF file whose pictures are compressed with HEVC (H.265), the same codec used for a lot of modern video. Apple made it the default camera format on iPhone and iPad with iOS 11 in 2017, under the setting called High Efficiency.
A HEIC photo is typically much smaller than the same photo as a JPG, which saves a lot of phone storage. But most browsers can't display it, Windows needs an extra extension to open it, and many websites refuse it as an upload.
