HEIC vs JPEG photo file format

HEIC stands for High Efficiency Image Container. The format is an updated variant of the High Efficiency Image Format (HEIF), traditionally used by Apple across its mobile devices.

Apple uses HEIC for HEIF images. HEIF essentially saves images in higher quality than JPEG while also using less space thanks to advanced compressive technology. This space-saving file format uses High Efficiency Video Coding (HEVC) to compress and store images on device drives — taking up half the space of other image file formats, like JPEGs.

Each HEIC file uses the .heic or .heics extension, depending on the number of images inside. The file also contains the relevant metadata describing each image’s size, resolution, location, and more.

The requirements and main use cases of HEIF were defined in 2013.[4][5] The technical development of the specification took about one and a half years and was finalized in the middle of 2015.[6]

Apple was the first major adopter of the format in 2017 with the introduction of iOS 11 using HEIC variant. While HEIC became the standard for iPhones, it remains possible to revert the settings to allow photos to be recorded in the more recognizable JPEG format.[7]
