Since iOS 11, iPhones have saved pictures in HEIC file format by default setting. HEIC — Apple's HEIC format — is highly efficient: it generates pictures with roughly half the storage of comparable JPEGs while keeping great image quality.
However there is a major catch. HEIC is an Apple-centric file type which is not broadly compatible outside the Apple ecosystem. PC users, non-Apple phones and many websites cannot open HEIC photos lacking extra apps.
Converting HEIC to JPG is the critical process that makes iPhone images usable on all devices. Typical situations that require conversion include transferring images to PC users, posting pictures to online platforms that do not accept HEIC.
Apple website Mac owners have a simple conversion path. Just open the HEIC file in Preview, navigate to File, then Export and choose JPEG as the file type.
On Windows, online conversion tools manage HEIC to JPG conversion with no software installation. Add the HEIC file and save the converted JPG.
