HEIC libraries for Go

The Go standard library has no HEIC support. Two options:

• libheif Go binding (github.com/strukturag/libheif/go/heif) lives in the libheif repository. It decodes and encodes HEIC and AVIF and registers with image.Decode. Needs cgo and an installed libheif.
• gen2brain/heic decodes HEIC without cgo: it uses a system libheif if present, otherwise a decoder compiled to WebAssembly. Read-only. Check the license of the embedded decoder before shipping it (see its page).

Pick the libheif binding when you need to write HEIC or already depend on cgo; pick gen2brain/heic for easy cross-compilation.

gen2brain/h265 (MIT) is a pure Go HEVC and HEIC decoder and encoder from the same author, with no cgo or WebAssembly.

• gen2brain/heic gen2brain/heic is a cgo-free HEIC decoder for Go using WebAssembly or a system libheif. Convert HEIC to JPEG or PNG, read image sequences and Exif metadata.
• libheif (Go) The libheif Go package reads and writes HEIC and AVIF images with cgo. Decode HEIC with image.Decode, convert HEIC to PNG or JPEG, encode HEIC.
