When you’re looking for a fast and easy way to convert your e-books into different formats, ePUBee gets the job done quickly. You won’t find any extras with ePUBee, only the ability to convert files. You can use the ePUBee Online Converter or download the desktop app for Windows and Mac to convert books without an internet connection.

ePUB Converter accepts most e-book formats and is easy to use. Just select the converter you want and upload your file to convert ePUB files to different e-book formats.

Sometimes e-book converters get hidden along with other types of file converters. Convertio is one of those web apps that converts thousands of file formats, e-books included. Converting e-books with Convertio is easy. Just upload your file, choose an e-book format, and you’re done. There's even a Convertio extension for Google Chrome.

Another free and easy-to-use online ePUB converter is Zamzar. Zamzar converts thousands of file formats, not just ePUB files. You can even convert PDFs to ePub files. After you’ve converted a file, be sure to download it within a day; after that, Zamzar will delete it.

If you need any extra ePUB conversion services, such as larger file sizes and online storage, you can sign up for a subscription. You can also download the Zamzar extension for Google Chrome.

Ebook Converter is a mobile app for Android devices that converts e-books into all the popular formats. The app also allows you to change the destination directory, select a cover, add an author name, and specify the book title.

When you want a choice between converting ePUB files online or in an app, check out File Converter. With File Converter, you get an Android app and an online converter, both of which are easy to use and capable of converting most file types beyond just e-books.

To ePUB works the same as most of the web apps: Just upload your e-book and To ePUB does all the hard work. You can convert multiple files simultaneously and download each on as soon as it's finished converting, which should only take a few seconds.
