LRF to TCR conversion is the process of transforming an ebook file in Sony's LRF (Broadband eBook / BBeB) format into the TCR (Psion/Cobrasoft/TCR eReader) plain-text ebook format. This conversion extracts text, images and basic layout from the LRF container and re-encodes them into the simpler, widely supported TCR structure so the ebook can be read on TCR-compatible readers or apps.

LRF is a proprietary ebook format developed by Sony, primarily used for their devices but limited in compatibility. TCR is a more widely supported text-based ebook format favored for its simplicity and smaller file size. While LRF supports complex formatting, TCR offers better compatibility across diverse e-readers.
Keep individual LRF source files under 250 MB for fastest processing; smaller files (under 50 MB) convert most reliably and quickly.
To preserve quality, use the conversion option that keeps images at original resolution; downscale only if you need smaller TCR output for low-memory devices.
For large libraries, use batch conversion but split very large multi-megabyte LRFs into smaller files when possible to avoid timeouts.
Be aware that TCR is a simpler, text-focused format: complex layouts, advanced CSS, and interactive elements in LRF may be lost or flattened.
