Starting with iOS 11, iPhones have saved pictures in HEIC file 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, non-Apple phones and many websites cannot open HEIC files lacking extra apps.
Converting HEIC to JPG is the critical action which makes iPhone images usable on all devices. Typical situations that more info require conversion include transferring images to PC users, uploading photos 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 pick JPEG as the format.
Windows PC users, web-based converters process HEIC to JPG conversion requiring no downloads. Select the HEIC image and get the resulting JPG.
