AZW3 to AVIF conversion is the process of extracting visual content (typically cover images and embedded graphics) from an AZW3 ebook file and converting those images into the AVIF image format. This conversion lets users produce smaller, high-quality images from ebook assets for web use, archival or device compatibility while the text content remains in the ebook container or is processed separately.
