Since iOS 11, iPhones have saved photos in HEIC file format by default setting. HEIC — Apple's HEIC format — is technically impressive: it produces images with approximately half the storage of similar JPEGs while maintaining excellent visual quality.
Yet there is a important issue. HEIC is an Apple-proprietary format that is not widely supported away from the Apple devices. Windows computers, Android phones and most web platforms cannot open HEIC photos with no additional software.
Converting HEIC to JPG is the critical process which makes iPhone photos universally shareable. Common scenarios needing conversion are sending iPhone photos to non-Apple users, adding images to websites that do not accept HEIC.
Apple Mac owners have a heic to jpg high quality simple method. Just open the HEIC image in Preview, go to File, then Export and pick JPEG as the output format.
Windows PC users, web-based converters handle HEIC to JPG converting with no software installation. Add the HEIC file and save the converted JPG.
