1. What is HEIC and Why Can't Windows PC Open It?

Starting with iOS 11, Apple adopted HEIC (High Efficiency Image Container) as the default image format for camera captures on iPhones and iPads. HEIC uses advanced HEVC compression to store photos at half the file size of traditional JPEG images without sacrificing quality.

However, because HEIC is a proprietary Apple format, Windows PCs, Android devices, website upload portals, and government application forms often throw error messages when users try to view or upload `.heic` files.
