Starting with iOS 11, iPhones have saved photos in HEIC format by default. HEIC — High Efficiency Image Container — is technically impressive: it produces images with roughly half the file size of similar JPEGs maintaining high photo quality.
Yet there is a major catch. HEIC is an Apple-centric file type which is not broadly compatible outside the Apple ecosystem. PC users, Android phones and many websites cannot open HEIC photos with no additional software.
Transforming HEIC to JPG is the necessary step making iPhone pictures compatible everywhere. Common scenarios needing conversion are sending iPhone photos to non-Apple users, adding images to websites incompatible with HEIC.
People with Macs enjoy the simplest method. Open the HEIC photo in Preview, go to File, then Export and pick JPEG as the format.
Windows PC users, web-based converters here process HEIC to JPG conversion requiring no software installation. Select the HEIC file and save the converted JPG.
