プロジェクトの歴史

The v1.0.0 release in February 2018 was billed as the first still-image decoder release and already covered HEIF features such as tiled images, alpha channels, thumbnails, EXIF/XMP metadata, depth channels, multiple images, image transformations, and overlays.

The v1.7.0 release in June 2020 added AVIF reading and writing through libaom and described a plugin architecture that let encoders reuse HEIF infrastructure while selecting AV1 compression.

The v1.12.0 release in May 2021 added MIAF conformance handling, premultiplied-alpha signaling, AV1 sequence-header parsing for the av1C box, and AVIF pixi-box writing. The v1.22.0 release in May 2026 broadened the library toward generic image components and a reworked ISO/IEC 23001-17 lossless-image codec implementation.

採用の歴史

libheif became a common Unix package because it gave image applications and shell workflows a reusable way to read HEIC files from Apple-oriented ecosystems and AVIF files from web-image ecosystems without each application implementing the container stack itself.

Homebrew ships it with user-facing tools such as heif-convert, heif-enc, heif-dec, heif-info, and heif-thumbnailer, which made it useful both as a library dependency and as a command-line conversion utility.

使われ方

Typical package use is format conversion, image inspection, thumbnail generation, and linking higher-level image software against a shared HEIF/AVIF implementation. Codec details are delegated to companion libraries or plugins such as libaom for AV1 support.

パッケージ好きにとっての重要性

libheif matters to packagers because the visible package is small, but its usefulness depends on codec policy, optional dependencies, plugin choices, and file-format brands. It is the sort of package where build options decide whether users get HEIC-only, AVIF-capable, or broader modern-image support.

It also marks the shift from classic single-image formats toward containerized image formats that carry auxiliary images, metadata, sequences, depth, alpha, HDR, and codec-specific boxes.
