Apple's HEIC (High-Efficiency Image Container) is great for saving space, but not so great for compatibility. Many APIs and libraries are optimized for older, more universal formats like JPEG. The beauty of Python is its vast ecosystem of libraries that can solve almost any problem. This little script was the key that unlocked the entire project.
