As an eBook reader, we may always find there are some eBooks have wrong metadata or miss some important information, especially when the book is downloaded from the internet such as torrent sites, unfortunately, it's always ePub format.
But don't worry, there are many useful tools can help us edit the epub books metadata, in this post, I will recommend you a very powerful ePub metadata editor, it's free and very easy to use.
Someone may don't know what's the meaning of metadata, in fact it's very simple, metadata is the basic information of a book, including the book title, cover, author, publisher and publish data, ISBN or ASIN number, sometimes it contains a brief introduction of the book. It helps us identify the book and manage our eBooks in an easy way.

Jonny Greenwood joined Epubor since 2011, loves everything about eBooks and eReaders. He seeks the methods to read eBooks more freely and wants to share all he has got with you.
I would love to have a metadata editor that can just edit the metadata and nothing else. Having my books messed up on my reader because the title is too long or in the wrong order because of the way the metadata has been used is a pain (and a lot of work to fix!)
This software only allows you edit the metadata, not create a new copy of ebook.
