HEIC is Apple’s proprietary version of the HEIF or High-Efficiency Image File format. This newer file format is intended to be a better way to save your pictures, making your images smaller in terms of data while retaining high quality.
Is HEIC better than JPG?
Yes, HEIC is better than JPG in many ways — specifically, in its ability to compress pictures into a small file size without losing image quality. The sticking point is the issue of what apps and devices also support HEIC. While more developers are adopting HEIC every day, it’s still not as commonly accepted as the tried-and-true standard, JPG.
