HEIC (High Efficiency Image Coding) is an image file format developed by MPEG (Moving Pictures Experts Group) for storing multiple and individual images. Unlike JPEG, HEIC uses both lossless and lossy compression to deliver a small file size with high-quality photos. Today, Apple devices, later than iOS 11, are using HEIC as their native image format.
PNG (Portable Network Graphics) is a raster image file format released in 1996 as a replacement for JPEG. That said, PNG uses lossless compression that gives it a small file size while still maintaining the original image quality. Today, PNG format is widely used to share image graphics over the internet and is supported by programs like Paintshop Pro, Adobe Photoshop, Microsoft Paint, Apple’s Preview, etc.
