avifdec decodes AVIF (AV1 Image File Format) images to standard formats like PNG, JPEG, or Y4M. AVIF is a modern image format offering superior compression and quality compared to JPEG.
The tool is part of libavif and enables viewing and converting AVIF images to more widely supported formats.

-c, --codec format

Output format (png, jpg, y4m)

JPEG quality (1-100)

Bit depth for output

Display image information only

Ignore ICC color profile

Ignore EXIF metadata

Decode specific frame from animation

- HDR support (10-bit, 12-bit)
- Wide color gamut
- ICC profile preservation
- EXIF metadata extraction
- Animation frame selection

Output format support depends on compile-time options. Large images may consume significant memory. HDR content may not display correctly in non-HDR-aware viewers.

avifdec was developed as part of libavif by Joe Drago and the Alliance for Open Media, released around 2019 to support the new AVIF format standardized by AOM.
