An AVIF (AV1 Image File Format) file is a relatively new image format derived from the AV1 video codec. It offers efficient compression for high-quality images at smaller file sizes compared to older formats like JPEG, PNG, and even WebP.
AVIF supports a wide range of features, including high dynamic range (HDR), wide color gamut, and 8-, 10-, and 12-bit color depths. It also supports transparency and progressive loading. Developed as an open, royalty-free format, AVIF aims to be a versatile and future-proof choice for web and digital image usage.
However, not all browsers and image viewers fully support AVIF.
