HEIC (High Efficiency Image Container) is an image format used for storing photos captured on smartphones. Many device manufacturers, including Apple, Samsung, and Google, have adopted HEIC as it’s an effective way of storing photo files without losing data.
However, HEIC is still relatively new, and does not enjoy the same level of broad support as the older JPG format (aka JPEG). This can lead to issues when trying to upload an HEIC file to certain websites and apps. Converting an HEIC file to JPG is relatively simple to do.
It's easy to convert HEIC to JPEG when you use the Preview application that comes on every in Mac. It takes just a few steps to convert your image file to a more recognizable format.
