AVIF to AZW3 conversion is the process of transforming image data encoded in the AVIF format (a modern, high-efficiency image container based on AV1) into the AZW3 format used by Kindle devices and e-readers to embed images inside ebook documents. This conversion typically involves extracting or rasterizing AVIF images and packaging them in a Kindle-compatible AZW3 container, often as part of creating or updating eBooks while balancing image quality and file size.
