LRF to FTS conversion is the process of transforming an ebook in Sony's LRF (Broadband eBook) format into the FTS format used by certain ebook readers and library/catalog systems. This conversion extracts the textual content, images, and metadata from the LRF package and repackages them into the FTS structure while preserving layout and reading order where possible.

LRF is a proprietary ebook format primarily used by Sony readers, often limited in compatibility. FTS is a more flexible and widely supported format offering enhanced features like improved navigation and annotation. While LRF files may be outdated, FTS ensures better usability on modern devices.
Keep individual LRF files under 50–100MB for faster uploads and reliable processing; larger files may require more memory and time.
For best quality preservation, choose the ‘high’ FTS quality option to retain image resolution and complex layout; choose ‘compact’ for lower file size when images are unimportant.
When converting many books, use batch conversion with archives (ZIP) to process multiple LRF files at once and monitor conversion logs for errors.
LRF can include proprietary styling and embedded fonts that may not map perfectly to FTS; expect minor layout shifts and reflow differences for complex page designs.
