HEIC is Apple’s proprietary version of the HEIF or High-Efficiency Image File format.

However, Windows Explorer doesn't recognize the file format and you cannot see thumbnails of the images. Here's how you can fix that problem so your iPhone and iPad Photos work just fine in Windows! This works great on Windows 11 too!
