Since iOS 11, iPhones have saved pictures in HEIC file format by default setting. HEIC — Apple's HEIC format — is highly efficient: it generates pictures with roughly half the storage of similar JPEGs maintaining great image quality.
However there is a major catch. HEIC is an Apple-centric file type not universally accepted beyond the Apple environment. Windows PCs, non-Apple phones and most online services do not support HEIC files without special programs.
Changing HEIC to JPG is the essential action making iPhone pictures universally shareable. Frequent cases needing conversion are sending iPhone photos to non-Apple users, adding images get more info 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.
For Windows users, browser-based tools manage HEIC to JPG converting with no setup. Add the HEIC photo and save the finished JPG.
