SNB to HDR conversion is the process of transforming an SNB ebook file (commonly used by specific e-reader apps and note-taking platforms) into an HDR ebook format that supports high-dynamic-range imagery or a header-based ebook package depending on the HDR variant. This conversion extracts text, images, and layout data from the proprietary SNB container and re-encodes them into the HDR structure so the resulting file can be opened by HDR-compatible readers or workflows.
