Understanding Both Formats
JPG: The Universal Standard
JPEG (Joint Photographic Experts Group) has been the dominant image format since 1992. It uses lossy compression to reduce file sizes while maintaining acceptable quality.
HEIC: The Modern Challenger
HEIC (High Efficiency Image Container) arrived in 2017 with iOS 11, promising better compression and more features.
