FICTIONBOOK to AVIF conversion is the process of extracting visual content from an FB2 (FICTIONBOOK) document—such as embedded cover images, illustrations, or pages exported as images—and re-encoding those images into the AVIF image format. This conversion is used when you want smaller, higher-compression images with modern features (HDR, alpha) from ebook artwork or screenshots originally packaged inside FB2 files.
