JPEG (High Efficiency Image Container) is Apple's image format introduced with iOS 11. It provides better compression than JPEG while maintaining image quality, but has limited compatibility with non-Apple devices.

Does converting PNG to JPEG lose quality?

No quality loss occurs during conversion. JPEG images are decoded and re-encoded as JPEG, maintaining the original image quality. However, JPEG uses lossy compression, so some minimal quality reduction may occur.
