Our software undergoes regular verification via independent antivirus reports to ensure total security.

2 Does Epubor Ultimate support mobile devices like Android or iOS?
A: Currently, Epubor Ultimate is a desktop-based solution compatible with Windows and macOS only. It does not run directly on iPad, iPhone, or Android devices.
3 What are the limitations of the free trial?
A: The trial version allows you to convert the full content but only outputs a 20% sample of each book in a text-only format. The full version removes these restrictions and preserves 100% of the original formatting.
4 Why is Epubor Ultimate the only tool that works for Kindle for Mac?
A: Amazon frequently updates its encryption on macOS to block third-party tools. Thanks to our 13 years of experience, we utilize a unique decryption kernel that doesn't rely on outdated methods, making us the only reliable choice for Mac users today.
5 Is it safe to use my Amazon account with Epubor?
A: 100% Yes. Unlike some new tools that may require built-in browser logins, Epubor Ultimate works locally. It only accesses the books already downloaded to your computer via official apps. We never ask for, store, or transmit your Amazon credentials to any server. Your account remains completely untouched and safe.
6 Can I use one license on both my Windows PC and Mac?
A: Our standard license is bound to one operating system (1 PC or 1 Mac) to ensure the highest level of technical support and updates. However, we do offer discounted bundles if you need to manage your library across different platforms. If you upgrade your computer, you can easily de-register the old machine and activate the new one. If you want to purchase family license, please contact us via epubor.service@gmail.com to get the biggest discount.

I have to give your staff and software Ultimate a rave review. It's well thought out, reasonably easy to use, and the online help documents are some of the most helpful I've seen. There is alot of information on kindle conversions out there but most of it is difficult to understand, to follow, and to be successful. For me your software seems to pull it all together with one tool to decrypt and convert to epubs. Not that it is totally easy dealing with Kindle roadblocks like KFXs, etc but your documentation saved the day.
I had over 30 books purchased from Kindle and have been frustrated that kindle makes it so hard to make an epub archive that can be used on other readers like kobo; as if you don't really own the books you purchase from them. Your Ultimate allowed me to succeed and also allowed me to archive purchased kobo books and make epub archives practically without effort.
Congratulations and thank you!
I just bought Epubor Ultimate.

Tried to remove DRM on the newly downloaded file ... success with ONE book.
Failed for the rest.
Epubor Ultimate has turned out to be a steaming pile of waste of money.
