MOBIPOCKET Books files are widely used for eBooks but have limited compatibility with some modern devices. HRZ offers improved compression and enhanced support across newer eBook readers. While MOBI focuses on legacy and Amazon devices, HRZ is gaining traction for optimized performance and broader accessibility.
Keep individual MOBI files under 100–200 MB for optimal upload and processing speed; very large illustrated books may require higher limits.
To preserve quality, choose the high image-quality HRZ preset and disable aggressive compression; embedded fonts and CSS are typically retained but test complex layouts.
For batch conversions, upload files as a ZIP or use a batch API to process multiple MOBIs; convert in groups of 10–50 to avoid timeouts.
Be aware that MOBI's proprietary Kindle-specific features (DRM, Kindle cloud annotations, or KF8-only interactive elements) may not transfer; DRM-protected MOBIs cannot be converted without first removing DRM.
