What is HEIC? Apple's iPhone Image Format Explained

HEIC (High Efficiency Image Container) is Apple's modern image format, used by iPhones since iOS 11 to save storage space. While efficient, it creates compatibility headaches when sharing photos with non-Apple devices.

Why Apple Chose HEIC

HEIC uses the HEVC (H.265) video codec to achieve roughly 50% smaller file sizes than JPEG without visible quality loss. On a smartphone storing thousands of photos, this matters significantly.

The Compatibility Problem

Windows, Android, older Macs, and many web applications cannot open HEIC files natively. This makes HEIC terrible for sharing and editing outside the Apple ecosystem.

Quality and Compression

HEIC preserves image quality better than JPEG at smaller sizes. However, this advantage vanishes once you convert to JPEG or PNG for sharing, which most users must do anyway.

When HEIC is Fine

Keep HEIC on your iPhone for storage efficiency. Convert to JPEG or PNG only when sharing, editing, or uploading to the web.
