La storia

COME HEIC
È NATO.

2015

2017

HEIC — High Efficiency Image Container — is Apple's filename for HEIF (High Efficiency Image File Format), a 2015 specification from the same MPEG group that gave us HEVC video. When Apple shipped iOS 11 in 2017, iPhones defaulted to HEIC for new photos, cutting photo library sizes roughly in half overnight.

Technically HEIC is a container: it wraps HEVC-compressed image frames along with depth maps, live-photo video, burst bursts, and auxiliary data. A single HEIC file can hold a still image, its thumbnail, a short 3-second video (Live Photo), depth information for portrait mode, and EXIF metadata — all with roughly half the file size of the equivalent JPEG.

CURIOSITÀ E
ANEDDOTI.

One HEIC file can contain a still photo, depth map, and 3-second Live Photo video together.

HEIC uses the same codec (HEVC/H.265) that Blu-ray 4K discs use for video.

Apple iPhones shoot HEIC by default but silently transcode to JPEG when you share to a non-Apple device.

HEIC supports 10-bit color depth — useful for HDR photography.

Royalties on HEVC patents caused Android, Windows, and Linux to delay HEIC support for years.

PUNTI DI FORZA E
LIMITAZIONI.

Punti di forza

Roughly 50% smaller than JPEG at equivalent visual quality.
10- and 12-bit color depth supports HDR photography.
Container format holds depth, Live Photo, bursts, and thumbnails in one file.
Supports transparency and multi-image sequences.
Built into iOS, macOS, and most modern Samsung and Google flagships.

Limitazioni

Patent-encumbered (HEVC) — Windows users must buy a $0.99 codec pack from the Microsoft Store.
Not supported by most web browsers or older image editors.
Sharing to non-Apple platforms usually auto-converts to JPEG, losing metadata.
Hardware decoding required for smooth performance; software decoding is CPU-heavy.
