Open IMG3 File

The IMG3 file format is mainly associated with Apple's iOS operating system for mobile devices like iPhones, iPads, and iPods. Key elements found in these files include device unique chip ID and personalization data. Additionally, some disk image files, such as ISO files or IMG files, can also be saved with the .IMG3 extension.

The iOS System File

In the realm of iOS, an IMG3 file is a firmware file used by the operating system. This kind of IMG3 file contains encrypted data that can be referenced by the device during a system restore or update. The IMG3 files used by Apple are not meant to be manually opened or viewed by the user. To perform a system update or restore, you would use iTunes which automatically accesses the necessary IMG3 files. For more information, see Apple iOS Update and Restore help.

The Disk Image File

Disk image files often use the .img extension, but can also sometimes be saved with .IMG3 extension. This kind of IMG3 file can be opened using disk image mounter software or can be burned to a disk. Software like OSFMount, Sync, and PowerISO can handle IMG3 as disk image files. They allow you to access the image and view the files contained within as if it were a physical disk.
