Tips & Limits for LRF to JFI Conversion
Keep individual LRF files under 25–50MB for fastest, most reliable conversion; large single files with many high-resolution images can slow processing.
To preserve reading quality, choose lossless or high-quality image settings for JFI when original LRF contains illustrations or complex layout.
For batch conversions, group similar-format LRF files together and use consistent metadata templates to reduce manual fixes after conversion.
Format limitation: LRF is an older Sony-specific format and may include proprietary layout features that require manual adjustment in JFI for perfect fidelity.
