LRF to DJVU conversion is the process of transforming an ebook in Sony's LRF (Broadband eBook) format into the DjVu (.djvu) image-based ebook format. This conversion extracts text and page images from LRF container files and repackages them into DjVu pages—often improving cross-platform readability and enabling efficient scanned-page compression for distribution and archival use.

LRF is a proprietary ebook format developed by Sony, primarily used for Sony Reader devices, with limited compatibility elsewhere. In contrast, DJVU is an open format recognized for its superior compression and quality retention, especially for scanned documents and graphic-heavy content. Converting from LRF to DJVU enables broader device support and more efficient file storage.
Keep source LRF files under 250 MB for smooth free conversions; 150–300 DPI page images give good legibility in DJVU without huge file sizes.
To preserve text quality, enable OCR/text-layer extraction when the LRF contains selectable text; otherwise use higher-resolution image conversion to avoid readability loss.
For large libraries, convert in batches of 10–50 files to reduce memory spikes; use a desktop batch tool for hundreds of files.
Note format limitations: LRF is a reflowable eBook container with text and simple layout, while DJVU is image-based—complex reflow or interactive elements from LRF may not be retained.
