SNB to RGBO conversion is the process of transforming an ebook saved in the SNB (a Samsung Notes/ebook stack format used by certain e-readers and note-taking apps) container into the RGBO ebook format, which packages reflowable text and graphics with Optimized RGBA-based rendering for compatible readers. This conversion extracts text, images, and metadata from the SNB source, maps layout and styles to RGBO structures, and outputs an RGBO file optimized for devices and apps that support that format.
