AVIF (AV1 image format) is a new open-source, royalty-free multi-channel image format. Compared with JPEG, PNG, and WebP images, AVIF images offer significantly smaller file sizes. They are currently compatible with Chrome, Firefox, and Android devices. It is based on the keyframes of the video format AV1, developed by the Alliance for Open Media (AOMedia) in collaboration with Google, Cisco, and Xiph.org. The AVIF format is already receiving considerable attention. Netflix states that it has better image quality and reduced file size than JPEG, PNG, and WebP formats. AVIF is a fascinating development with the potential to be widely adopted. JPEG has been around for decades, and there is a need for new advanced alternatives.
