Convert JPG to HEIC — Apple-Native Format
HEIC (High Efficiency Image Container) is Apple’s native image format used across iOS, macOS, and iCloud. It produces files 30-50% smaller than JPG at the same visual quality. If you work primarily in the Apple ecosystem, converting your JPGs to HEIC can save significant storage space on iCloud and your devices.
