Since iOS 11, iPhones have saved pictures in HEIC file type by standard. HEIC — Apple's HEIC format — is a great format: it produces photos with roughly half the file size of comparable JPEGs maintaining excellent visual quality.
However there is a major problem. HEIC is an Apple-proprietary file type which is not widely supported beyond the Apple ecosystem. PC users, non-Apple phones and most web platforms do not support HEIC images without special programs.
Changing HEIC to JPG is the necessary step making iPhone pictures universally shareable. Common scenarios needing conversion are sending iPhone photos to non-Apple users, adding images to websites incompatible with HEIC.
People with Macs have the easiest process. Open the HEIC photo in Preview, select File, then Export and select JPEG as the output format.
Windows PC users, browser-based tools process HEIC to JPG converting without any downloads. Select the HEIC check here image and get the resulting JPG.
