From iOS 11 onwards, iPhones store photos in HEIC format by default. HEIC — High Efficiency Image Format — is a great format: it produces images with approximately half the file size of equivalent JPEGs maintaining high photo quality.
Yet there is a major problem. HEIC is an Apple-centric format not universally accepted beyond the Apple ecosystem. Windows PCs, non-Apple phones and many websites do not support HEIC files lacking extra apps.
Converting HEIC to JPG is the critical heic to jpg mac process that makes iPhone images usable on all devices. Typical situations where this becomes a problem involve sharing photos to Windows users, posting pictures to online platforms that do not accept HEIC.
Apple Mac owners have the easiest process. Simply open the HEIC photo in Preview, select File, then Export and select JPEG as the output format.
For Windows users, browser-based tools handle HEIC to JPG converting without any setup. Upload the HEIC image and download the resulting JPG.
