avify

Batch convert images to AVIF with parallel encoding.

Supports RAW camera files (ARW, CR2, CR3, DNG, NEF, etc.), HEIC/HEIF, and standard formats (JPEG, PNG, WebP, BMP, TIFF, GIF).

Note: This is proof-of-concept code. It may be unreliable and is not actively maintained.

Install

cargo install avify

HEIC/HEIF support (optional)

HEIC requires the libheif system library. Enable with:

brew install libheif
cargo install avify --features heic

See build.sh for a script that builds a minimal decode-only libheif from source.

Usage

avify [OPTIONS] [FILES]...

If no files are given, converts all supported images in the current directory.

Options

Flag	Description	Default
-q, --quality	Encoding quality (0-100)	80
-s, --speed	Encoding speed (1-10, higher = faster)	10
-o, --outdir	Output directory for AVIF files	same as input
-m, --move-originals	Move originals to this directory after conversion
-t, --trash	Trash originals after conversion (macOS)
-x, --xmp	Apply Lightroom XMP sidecar edits

Examples

avify *.jpg

avify -q 90 -s 6 photo.arw

avify -o converted/ -m originals/

avify -x raw_photos/*.cr3

Features

• Parallel encoding via rayon — uses all CPU cores
