LRF to DBK conversion is the process of transforming an ebook file in Sony's LRF (Broadband eBook) format into a DBK (Dealer Book / Document Book) file used by certain ebook readers and retail systems. This conversion repackages text, images, layout and metadata so the content is readable and correctly formatted in DBK-compatible apps and devices.
