RB to HRZ conversion is the process of transforming an RB eBook file — a container format commonly used by specific eReader software and publishing tools — into the HRZ eBook format, which may include a different internal structure, metadata schema, and compression profile. This conversion extracts the book content, images, and metadata from the RB package and repackages or transcodes them into an HRZ-compliant file so the book can be read or distributed by devices and apps that support HRZ.
