Since iOS 11, iPhones store pictures in HEIC file type by default setting. HEIC — High Efficiency Image Format — is technically impressive: it generates pictures with about half the file size of similar JPEGs while keeping high photo quality.
But there is a significant problem. HEIC is an Apple-proprietary format which is not universally accepted beyond the Apple devices. PC users, Android phones and most web platforms cannot open HEIC files without special programs.
Transforming HEIC to JPG is the critical action making iPhone pictures compatible everywhere. Frequent cases needing conversion include sending iPhone photos to non-Apple users, adding images to websites incompatible with HEIC.
People with Macs have the easiest method. Open the HEIC photo in Preview, go to File, then Export and pick JPEG as the website output format.
Windows PC users, web-based converters handle HEIC to JPG converting without any downloads. Upload the HEIC image and get the resulting JPG.
