Starting with iOS 11, iPhones have saved photos in HEIC file format by default setting. HEIC — Apple's HEIC format — is highly efficient: it creates photos with about 50 percent less storage of comparable JPEGs while keeping excellent visual quality.
But there is a significant issue. HEIC is an Apple-specific format that is not widely supported away from the Apple environment. Windows computers, Android devices and most online services cannot display HEIC website images without special programs.
Transforming HEIC to JPG is the necessary step making iPhone pictures universally shareable. Frequent cases needing conversion include sending iPhone photos to non-Apple users, uploading photos to social media without support for HEIC.
Mac users enjoy the simplest conversion path. Just open the HEIC image in Preview, navigate to File, then Export and choose JPEG as the format.
On Windows, online conversion tools manage HEIC to JPG conversion with no software installation. Add the HEIC file and save the converted JPG.
