Looking for the best bulk ebook converters?
The extensive range of digital book formats surely makes your life as a reader, author, publisher, and ebook library manager much more challenging. Here’s why you might need converters:
- Certain digital book readers don’t support ebooks from a specific library or store.
- Ebooks becoming obsolete due to the non-maintenance of certain digital book file types.
- Your ebook library attracts users with different reader devices and apps needing multi-format support.
In this article, I’ll introduce you to the finest ebook converters with batch processing. I’ve highlighted their features, ease of use, and efficiency to help you choose the perfect app.
6 Best Bulk eBook Converters
Here are my top six picks:
Online Ebook Converter – Best for Minimalistic UI
Online Ebook Converter is a free web app that can transform one digital book into another one. It’s also SSL-encrypted so there’s less possibility for hackers to intercept your device’s communication with the server to steal digital books.
Moreover, it creates a Delete from server button for each file so you can manually remove the uploaded content from the server. If you forget to delete, the server itself removes all uploads after 24 hours. Additionally, all the uploads and downloads are encrypted so that the developers themselves can’t access your content.

You can choose your own preferred encoding algorithm from 20+ options. |
