Starting with 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 50 percent less storage of comparable JPEGs maintaining high photo quality.
Yet there is a major problem. HEIC is an Apple-proprietary format that is not widely supported away from the Apple devices. Windows computers, Android phones and most web platforms do not support HEIC files lacking special programs.
Changing HEIC to JPG is the essential step which makes iPhone images universally shareable. Typical situations needing conversion are sharing photos to non-Apple users, uploading photos to social media without support for HEIC.
Mac users have a simple conversion path. Simply open the HEIC file in website Preview, select File, then Export and select JPEG as the output format.
Windows PC users, web-based converters handle HEIC to JPG conversion requiring no software installation. Add the HEIC photo and download the resulting JPG.
