For those who prefer to copy their iPhone images over to a Mac or Windows PC via the USB transfer method, our Tutorial series has explained how to convert HEIF-encoded media to the JPEG format using Apple's stock Preview app or a free app like iMazing HEIC Converter.
iOS 11 and macOS High Sierra debuted HEIF, Apple's new efficient image format meant to supplant JPEG by delivering the same or better quality at half the file size. That's great, but what about converting your HEIF photos into the more compatible JPEG format?
As you might know, Apple with iOS 11 and macOS High Sierra introduced a new space-saving image file format, called High Efficiency Image File Format (HEIF).
If you own an iPhone 7 and newer or a 2017 iPad Pro, you may have noticed that updating to iOS 11 defaults the Camera app to capturing photos in Apple's new High Efficiency Image File Format (.HEIC files) and videos in the High Efficiency Video Coding (HEVC or H.265) format instead of the ubiquitous JPEG and H.264 media formats.
