LRF to JFIF conversion is the process of extracting pages or images from Sony/PEB-compatible LRF ebook files and converting them into JFIF-format JPEG images. This conversion turns fixed-layout ebook pages into standalone image files (JFIF is a JPEG Interchange Format variant) suitable for image editing, archiving, or embedding in other documents.

LRF is a proprietary ebook format primarily used for Sony Reader devices, focusing on text and limited graphics. In contrast, JFIF is an image file format based on JPEG standards, optimized for storing photographic images with broad software support. While LRF focuses on ebook content, JFIF is ideal for standalone images and web compatibility.
Keep individual JFIF images under 5–10 MB for easy sharing; for long or image-heavy ebooks, consider splitting into multiple archives.
To preserve maximum visual fidelity, export at high quality (80–100) with minimal chroma subsampling (4:4:4) and a DPI of 300+ for print-ready images.
For large libraries, use batch conversion tools that preserve file naming (title_page_01.jfif) and support multi-threading to speed up processing.
LRF is primarily a reflowable/text-and-image ebook container adapted by Sony; some LRF files store text as vector data—those elements may be rasterized during conversion and lose selectable text.
