The JWPUB file format, used exclusively by the Jehovah’s Witnesses JW Library application, is a proprietary e-book container. In 2021, no official tool existed to convert JWPUB to the open EPUB standard. This paper analyzes the structure of the JWPUB format, identifies its similarities to EPUB, and documents the methodologies developed by the open-source community to extract, decrypt, and repackage JWPUB content into valid EPUB files. We present a technical workflow, evaluate its legal and ethical considerations, and provide a case study of successful conversion using Python scripts.
