Starting with iOS 11, iPhones have saved photos in HEIC format by default setting. HEIC — Apple's HEIC format — is highly efficient: it generates photos with about 50 percent less storage of comparable JPEGs while keeping great image quality.
However there is a significant catch. HEIC is an Apple-specific file type which is not broadly compatible outside the Apple ecosystem. PC users, Android phones and many websites cannot open HEIC files lacking extra apps.
Converting HEIC to JPG is the critical process which makes iPhone photos usable on all devices. Typical situations that require conversion involve sharing photos to Windows users, posting pictures to online platforms that do not accept HEIC.
Apple 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.
