About HEIC file
As of 2017 or to be more exact, iOS 11, Apple choose HEIC image format to be the default for taking photos on all their devices. That includes Mac OS High Sierra and newer releases. Even though MPEG developed HEIC format as a successor to JPG, the change has yet to come on major social platforms, devices, operating systems, web browsers, image processing apps, etc. The only disadvantage of the HEIC format is compatibility and lack of support that the JPG image format already has.
HEIC or HEIF is short for High Efficiency Image Container / Format, and it justifies its name with its features. Size-wise, HEIC photos are at least 50 % smaller than those in JPG format without any quality loss. Moreover, HEIC files have a 16-bit color range compared to JPGs 8-bit. That made HEIC images richer in color tones and adapted to camera hardware capabilities. HEIC files can also besides images contain and image sequences. Opening and editing the HEIC file is still tricky on most devices because there are not many adequate apps that can handle these files. That is why converting HEIC to PDF file format is an efficient option for viewing these files' content.
