DBK to SNB conversion is the process of transforming a document stored in the DBK format (a structured document bundle often used for indexed notes, annotations and embedded resources) into the SNB format (a compact single-file notebook format designed for fast loading and cross-platform reading). This conversion repackages the DBK’s pages, metadata, and embedded assets into SNB’s container while preserving layout, text content, and attachments where format compatibility allows.
