Starting with iOS 11, iPhones store photos in HEIC format by default. HEIC — High Efficiency Image Container — is a great format: 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 not broadly compatible beyond the Apple ecosystem. PC users, non-Apple phones and many websites cannot open HEIC photos with no additional software.
Converting HEIC to get more info JPG is the critical process that makes iPhone images compatible everywhere. Common scenarios where this becomes a problem involve sharing photos to Windows users, posting pictures to websites incompatible with HEIC.
People with Macs have the easiest method. Open the HEIC photo in Preview, go to File, then Export and pick JPEG as the format.
Windows PC users, web-based converters process HEIC to JPG conversion requiring no downloads. Select the HEIC file and get the converted JPG.
