AVIF (AV1 Image File Format) Compression Specification

Formula representation used for accurate calculations:

Target Bitrate / File Size = (AV1 Intra-Frame Prediction Block Size + Directional Transforms + 10/12-bit HDR Color Matrices) ÷ 8 Compression Efficiency: Up to 50% smaller than WebP and 70% smaller than JPEG at identical SSIM/PSNR visual index.

Calculation Example: A 4.8 MB JPEG photograph encodes into ~1.1 MB in AVIF format (-77% bandwidth saving) with full 4:2:0/4:4:4 chroma fidelity and stripped EXIF headers.
