What is HEIF Photos on iOS 11?
The High Efficiency Image Format (HEIF), known as ".heic", is a new image format releasing after iOS 11 and it is used on the new taken photos in iOS 11 by default. HEIF could be regarded as one of the great improvements in iOS 11 for it fixes the problem that photos take up too much storage space on iDevice and iCloud Photo Library by reducing the image size but remaining the image quality.
HEIF Photo Supported iDevices:
For now, the HEIF files or HEIC images only supports iOS device with iOS 11 and Mac with macOS High Sierra. Currently, the supported iOS devices include:
· iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone XS, iPhone XR, iPhone XS Max, iPhone X, iPhone 8, iPhone 8 Plus, iPhone 7, iPhone 7 Plus or later;
· iPad Pro (10.5 inch) and iPad Pro 12.9 inch (2nd generation) or later;
· Mac with macOS High Sierra or higher.
Before the process, please make sure you are using the supported iOS device and your iPhone or iPad is running iOS 11 now. Then you might follow the instructions as below to enable or disable High Efficiency Image Format on your device. After disabling HEIF image format, your iPhone or iPad will take pictures as JPEG format like before.
Step 1. Unlock your iPhone or iPad and launch "Settings" app on your device and tap "Camera" option.
Step 2. Under Camera page, please tap "Formats" option to set up photo formats when taking pictures and transferring to computer.
Step 3. To disable HEIC image format, simply tap to switch on "Most Compatible" from "High Efficiency" option under CAMERA CAPTURE section.
