What is EPUB (Electronic Publication)?
EPUB (Electronic Publication) is a widely used open standard for digital e-books and publications. EPUB files are designed to be reflowable, meaning the content adapts to different screen sizes and orientations, making it suitable for a variety of devices including e-readers, smartphones, and tablets.
EPUB supports text, images, and multimedia, and is commonly used for distributing e-books in formats that are easy to read on a wide range of devices. It’s supported by most e-book readers except Amazon Kindle, which uses its own proprietary formats.
How to open EPUB?
EPUB files can be opened with a variety of e-reader applications, such as Adobe Digital Editions, Calibre, and Apple Books.
On Windows, Calibre is a popular tool for reading and managing EPUB files, while macOS users can use Apple Books or other third-party apps like Calibre or BookReader.
EPUB is Developed by: International Digital Publishing Forum (IDPF)

What is LRF (Portable Reader File)?
LRF (Portable Reader File) is a proprietary ebook format developed by Sony for its Sony Reader devices. Based on the Broad Band eBook (BBeB) format, LRF files store formatted text, images, and metadata in a compact binary structure optimized for Sony's e-ink displays.
LRF files offer features like fixed page layouts, embedded fonts, and high-quality image display. Though Sony has since transitioned to more standard formats like EPUB, a significant library of legacy content exists in LRF format, particularly Japanese literature and manga published for early Sony Reader models. Supported extension is .lrf.
How to open LRF?
LRF files can be opened natively on Sony Reader devices, including the PRS-500, PRS-505, and PRS-700 models. For other platforms, dedicated software is limited since Sony discontinued support for this proprietary format.
Currently, the most effective way to access LRF content is through conversion. Ebook management software like Calibre can convert LRF files to more widely supported formats like EPUB or PDF. Some specialized applications like LibreOffice with appropriate extensions may also be able to read certain LRF files.
