Starting with iOS 11, iPhones have saved photos in HEIC format by default. HEIC — High Efficiency Image Format — is a great format: it produces images with roughly half the file size of similar JPEGs maintaining high photo quality.
However there is a significant catch. HEIC is an Apple-specific file type that is not widely supported away from the Apple environment. Windows PCs, non-Apple phones and many websites cannot open HEIC photos with no additional software.
Transforming HEIC to JPG is the necessary step which makes iPhone photos usable on all devices. Typical situations that require conversion involve sharing photos to Windows users, posting pictures to websites incompatible with HEIC.
People with Macs enjoy the simplest method. Just open get more info the HEIC image in Preview, navigate to File, then Export and choose JPEG as the file type.
For Windows users, browser-based tools handle HEIC to JPG converting without any downloads. Select the HEIC file and get the converted JPG.
