eBook Manager is a fast and easy to use application for organizing e-books on your computer and for transferring them from and to your Kindle e-readers.
It understands .mobi, .azw and .azw3 file formats and extracts and shows book metadata like author, title, description, publisher, language, comment and cover image. Books can be organized to collections in the library stored on your computer (but this information is not transferred to the reader).
To import the book from any place in the computer filesystem or to transfer it to the library or to the reader, just drag and drop it. You can also easily change the author or the title of the book.
eBook Manager is not a reader or a conversion tool yet.
To run eBook Manager you need macOS 10.13 or later and any Amazon Kindle e-reader.
