ELECTRONIC Publication to HRZ conversion is the process of transforming an EPUB digital book package — which contains XHTML content, images, CSS, and metadata — into the HRZ format, a compressed/packaged document container used for optimized distribution or proprietary reader systems. This conversion repackages resources, may apply compression and format adjustments, and preserves reading order and metadata so the content remains accessible in HRZ-compatible apps and devices.

ELECTRONIC Publication (EPUB) is a widely used open standard format for digital books, offering broad device compatibility and flexible layout options. On the other hand, HRZ is a specialized format focusing on optimized performance and compact file size, preferred in specific ecosystems. While EPUB prioritizes accessibility and compatibility, HRZ excels in efficiency and tailored use cases.
Keep individual EPUB files under 100–200 MB for faster, more reliable conversions; very large books with many images can increase processing time.
To preserve layout and quality, choose a low compression HRZ preset and avoid aggressive image re-encoding; test one sample chapter first.
For bulk conversions, use batch mode with consistent presets to ensure uniform output; monitor memory and CPU usage when converting many large EPUBs.
Format limitation: encrypted DRM-protected EPUBs cannot be converted until DRM is legally removed; complex interactive EPUB features (JS-driven widgets) may not fully translate to HRZ.
