Can AVIF Store Multi-Layer Composition Files?

While the AV1 Image File Format (AVIF) supports sophisticated container capabilities such as alpha channels, depth maps, and multiple image items, it cannot be used as a multi-layer composition format comparable to PSD or layered TIFF. AVIF is fundamentally designed for media delivery and compression efficiency rather than digital content creation and non-destructive graphic editing.

AVIF Container Architecture

AVIF is built on top of the ISO Base Media File Format (ISOBMFF), derived from the High Efficiency Image File Format (HEIF). Under this architecture, an AVIF file can technically hold more than one image. It allows for:

• Primary and Auxiliary Images: Storing a primary image alongside secondary data, such as an alpha transparency mask, gain maps for HDR, or depth information.
• Image Collections and Sequences: Storing multiple individual frames inside a single file, typically used for animations or burst shots.
• Derived Images: Basic operations like grid arrangements or alpha overlays directly referenced in the container metadata.

Why AVIF Cannot Replace PSD or TIFF Layers

Despite its ability to package multiple image items, AVIF lacks the essential mechanisms required for composition authoring:

• No Blend Modes or Opacity Stacks: Layered formats like PSD rely on complex raster operation pipelines, such as Screen, Multiply, Overlay, and non-destructive layer opacity controls. AVIF has no standard instructions to compute these interactions dynamically.
• Lack of Non-Destructive Elements: Composition formats store non-pixel data, including adjustment layers, vector shape paths, live text elements, layer styles, and smart objects. AVIF only stores encoded pixel data.
• No Authoring Toolchain Integration: Image editors (such as Photoshop, GIMP, or Affinity Photo) interpret AVIF files strictly as flattened, single-plane exports. There is no standardized metadata specification within AVIF to instruct design software on how to reconstruct an editable layer hierarchy.

Delivery Format vs. Working Format

AVIF functions as a final-stage distribution format. Its purpose is to deliver high visual quality at minimal file sizes across the web and digital applications.

By contrast, PSD and layered TIFF files are authoring formats meant to preserve all historical, geometric, and compositional data without regard for web delivery performance. For any workflow requiring ongoing edits to separate visual elements, layered TIFF, PSD, or OpenEXR remain the appropriate choices, with AVIF serving strictly as the final flattened export target.
