AFF to LRF conversion is the process of transforming files in the Advanced File Format (AFF), commonly used for vector drawings and structured graphic documents, into Sony/BBeB LRF (BroadBand eBook) files, a compressed format historically used for e-readers. This conversion repackages drawing and layout data into the LRF container, optimizing for compatibility with devices or apps that accept LRF while preserving vector fidelity where possible.

AFF files typically use the MIME type application/x-aff and contain DRM-protected eBook content used in early Sony Reader devices. LRF files use the MIME type application/x-lrf and are designed for faster rendering and improved compression. Both formats rely on Sony's proprietary codecs to ensure secure and efficient eBook delivery.
The LRF (.LRF) format is commonly used for ebook. Understanding its characteristics can be helpful when converting to or from other formats like AFF.
While specific technical details aren't available here, LRF files generally serve the purpose of storing ebook effectively within their domain.

AFF files are proprietary to Sony's older eBook system, primarily used for storing eBooks with embedded DRM. LRF, on the other hand, is a more streamlined format optimized for Sony Reader devices offering improved performance and support. While AFF files can be bulky and less flexible, LRF files provide better compression and reading speed on compatible devices.
Keep individual AFF source drawings below 50–100 MB for fastest, most reliable conversion; very large vector files may slow or fail conversion.
To preserve line art and scalability, select the "full vector preservation" or "low rasterization" LRF quality option when available.
For complex drawings with many embedded images, flatten or downsample extremely high-resolution bitmaps before converting to reduce output size without noticeably affecting on-screen quality.
Use batch conversion for multiple AFF files, but limit batches to 20–50 files depending on size to avoid timeouts or memory limits.

Format-specific limitation: LRF is primarily an e-book container and may not support certain interactive drawing features, advanced layer effects, or editable vector objects—those may be rasterized during conversion.
