RB to PCD conversion is the process of transforming an ebook or document saved in the RB (RocketBook/ReadableBook-style binary ebook) format into the PCD (PocketCatalog Document) format used by certain e-reader and cataloging applications. The conversion remaps RB's internal layout, metadata, and embedded assets (images, fonts) into PCD's page-oriented, compressed structure so the output is readable and indexed by PCD-compatible readers.

RB files are generally proprietary and less supported across different platforms, whereas PCD files offer better compatibility and are widely accepted in professional imaging software. While RB focuses on raw data, PCD is optimized for compressed photo storage, making it more efficient for sharing and editing.
Keep individual RB source files under 100–200 MB for fastest, most reliable conversions; larger files can be processed but may require more memory and time.
To preserve reading quality, choose the high-quality PCD option and lossless image compression when your RB contains detailed illustrations or fixed-layout pages.
For batch conversion, group RB files into archives or use a queue tool; process batches in smaller groups (5–10 files) to avoid memory spikes and maintain consistent metadata mapping.
DRM-protected RB files cannot be converted without user-provided decryption keys or removing DRM using legal means; converters only handle DRM-free RB content.
