TCR to LRF conversion is the process of transforming an ebook or document stored in TCR (Psion/E-book compressed text format) into LRF (Sony Portable Reader eBook format). This conversion repackages text and images into the LRF container, adjusting compression and layout metadata so the resulting file is readable on devices and apps that support Sony's LRF format.

TCR files generally use the MIME type application/x-tcr and contain text-based ebook data primarily for older devices.

TCR files are typically used as a proprietary eBook format with limited device support, whereas LRF files offer broader compatibility and improved reading features. While TCR focuses mostly on raw text storage, LRF enhances the user experience through better formatting and smaller file sizes. Choosing LRF ensures your ebooks are accessible on modern Sony eReaders and compatible software.
Keep individual source TCR files under 50–100MB for fastest processing and best compatibility; very large single files may fail on some devices.
To preserve quality, choose the high-quality LRF output and avoid aggressive image downsampling; text-only TCRs will retain native clarity.
For many files, use batch conversion tools but convert in small groups (10–20 files) to avoid memory/timeouts on web services.
Be aware that TCR is an older, limited ebook container—complex modern formatting (CSS, advanced layouts) may not convert perfectly to LRF.
