From iOS 11 onwards, iPhones store images in HEIC format by default. HEIC — High Efficiency Image Format — is a great format: it creates photos with about 50 percent less storage of comparable JPEGs while keeping great image quality.
But there is a significant issue. HEIC is an Apple-specific file type which is not widely supported outside the Apple devices. PC users, Android phones and most web platforms cannot open HEIC photos with no additional software.
Transforming HEIC to JPG is the critical process that makes iPhone images compatible everywhere. Common scenarios where this becomes a problem involve sharing photos to Windows users, adding images to websites incompatible with HEIC.
People with Macs have the easiest process. Open the HEIC photo in Preview, select File, then Export and pick JPEG as the output format.
For Windows users, web-based converters handle HEIC to JPG converting without any downloads. Upload the HEIC image and get the resulting JPG.
