FTS to LRF conversion is the process of transforming image-based FTS files—often a proprietary or less-common image container—into LRF, a Sony/BBeB-compatible eBook/image format that packages images and layout for portable readers. This conversion repackages image data and metadata to match LRF specifications, preserving page order and visual fidelity while creating a file usable by LRF-compatible devices and apps.

FTS files typically use the MIME type application/octet-stream and are primarily used in specialized applications or devices. LRF files have the MIME type application/x-mobipocket-ebook and are commonly associated with Sony Reader devices. The conversion process involves re-encoding the file content to match the LRF codec standards optimized for e-book display.
The LRF (.LRF) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like FTS.

FTS files are often proprietary and less widely supported, limiting their usability across various devices. In contrast, LRF is a more versatile format favored for e-books due to its optimized compression and enhanced compatibility. Choosing LRF over FTS ensures a smoother reading experience on common e-reader platforms.
Keep individual FTS source images below 5–10 MB each to avoid memory issues on conversion; total optimal project size under 250 MB for smooth processing.
To preserve visual detail, choose High quality LRF output and lossless/low-compression image settings; use PNG input where possible for line art and text.
For large numbers of files, use batch conversion with consistent naming and resolution settings to maintain layout order and speed up workflow.
Be aware that LRF is a fixed-layout format: reflowable text is not supported, so conversions of text-heavy FTS images will remain image-based and not selectable/searchable.
