AV1 Image File Format
MIME type: image/avif
AVIF is a modern image format based on the AV1 video codec, developed by the Alliance for Open Media. It offers significantly better compression than JPEG and WebP - typically 30-50% smaller files at the same visual quality. As of 2026, AVIF has 93% browser support.
AVIF uses the AV1 intra-frame codec for still image compression. It supports 8-bit, 10-bit, and 12-bit color depths, 4:2:0, 4:2:2, and 4:4:4 chroma subsampling, and both lossy and lossless compression. The format is based on the ISOBMFF (ISO Base Media File Format) container, the same used by HEIF/HEIC. Encoding is CPU-intensive but decoding is fast, making it ideal for web delivery.
AVIF (AV1 Image File Format) is a modern, open-source image format that compresses images 30-50% smaller than JPEG while maintaining the same visual quality. It's supported by Chrome, Firefox, Safari, and Edge.
AVIF generally achieves 20-30% better compression than WebP, especially for photographs. However, WebP encodes faster and has slightly broader legacy support. For new projects, AVIF is the better choice.
Most modern browsers (Chrome, Firefox, Safari, Edge) can display AVIF images natively. For editing, use GIMP, Photoshop (with plugins), or convert to PNG/JPEG using BriskTool's image converter.
