Reading guides

Choose the task you need

Start with the opening guide if a book is new to you. The offline guide explains preparation before travel or a lost connection. Library management covers collections, edited details and safe backup restoration. The formats guide compares EPUB and PDF and explains why changing a filename does not convert a book.

These guides describe the current application, including its limits. They do not promise a commercial book catalogue, ebook conversion, OCR, DRM removal or cross-device accounts. For a specific failure, the Help page begins with checks that avoid deleting your saved books.
