MOBIPOCKET Books Prc is a proprietary ebook format primarily used on older Kindle devices, while SPH is a more versatile format supporting broader multimedia content. PRC files often have limited device compatibility compared to the flexible SPH format, which is optimized for modern ebook readers. SPH offers better support for enhanced formatting and interactive features than the traditional PRC format.
Optimal file sizes: for best performance aim for PRC source files under 50–100 MB; larger files with many images can slow conversion and delivery.
Quality preservation: choose SPH uncompressed or high-quality image settings to retain image clarity and preserve embedded fonts and layout where possible.
Batch conversion advice: convert similar files (same layout and size) together and use consistent quality settings; split very large collections into smaller batches to avoid timeouts.
Format-specific limitation: PRC files with DRM cannot be converted; embedded scripts or interactive features in PRC may not be fully supported in SPH.
