SNB to DBK conversion is the process of transforming an ebook package in the SNB format (commonly used by certain e-reader apps and note-taking devices) into the DBK ebook container format. This conversion repackages text, images, annotations and metadata so the content is readable and navigable by DBK-compatible readers while preserving layout and searchable text where possible.
