Apple has just released iOS 11, and one major change is the way recent iOS devices (iPhone 6s and later) store photos. Apple has adopted HEIF (High Efficiency Image Format), which creates photos that take up less space than JPEGs. This is great for the storage on your iOS device, and for your mobile bandwidth, if you sync your photos to iCloud Photo Library.
