Frequently Asked Questions
5 questions
No, not directly. Kindle books are locked in Amazon's proprietary KF8 format. However, you can read Kindle books on Kobo using the Kindle app on tablets/phones. Some DRM-free books from Amazon can be converted to EPUB for Kobo, but this violates Amazon's terms of service. For DRM-protected content, you're locked into Kindle devices.
