From iOS 11 onwards, iPhones save images in HEIC format by default. HEIC — High Efficiency Image Format — is a great format: it creates photos with about 50 percent less storage of comparable JPEGs while keeping great image quality.
But there is a significant catch. HEIC is an Apple-specific file type which is not broadly compatible outside the Apple ecosystem. PC users, non-Apple phones and most online services do not support HEIC files lacking special programs.
Changing HEIC to JPG is the essential action which makes iPhone photos universally shareable. Frequent cases needing conversion are sending iPhone photos to non-Apple users, adding images to social media without support for HEIC.
Mac users enjoy the simplest method. Just open the HEIC image in Preview, go to File, then Export and choose get more info JPEG as the format.
On Windows, online conversion tools process HEIC to JPG conversion requiring no software installation. Select the HEIC file and get the converted JPG.
