PDFelement-Powerful and Simple PDF Editor

Get started with the easiest way to manage PDFs with PDFelement!

Reading books is one of the most popular hobbies. And now, we don't need physical copies of books to enjoy reading. Digital copies called eBooks exist now.

The thing is that there are different file formats for eBooks. And a reader may not support one or two formats. So, you'd want to convert them first. Of course, you would need a program to do that. Here, we will look at the 5 best eBook converters online.

What A Good eBook Converter Should Provide

We used a set of criteria to decide which online converters are the best. This list is a product of extensive research, not blind picking. So, rest assured that you will find these recommendations helpful.

Here are the factors that we considered:

Support for Multiple Output and Input Formats

The more formats the converter supports, the higher its grade is since it directly shows how helpful the program is. You can always rely on that converter if it supports all eBook file types.


A good program has a user-friendly layout; you only need it to convert eBooks, so there's no reason for it to be complicated.

Batch Converting Feature

If the online eBook converter allows you to convert in batches, you don't have to repeat the process for multiple files. It's a huge time saver.


Does the online eBook converter give you customization options? Can you edit the interface, so it is easier to use, or could you change the titles and covers of converted files?

Data Security

Privacy and security are always significant concerns. The top eBook converter should not steal your data or impose any security risk.

Frankly, Online Converter looks like a project of a high-schooler. Another downside is that it does not allow batch conversions. But if you insist on not spending, Online Converter is your best choice.

Why Are eBooks Better Than Printed Books?

Most book lovers would prefer printed books. There's magic in turning the pages of a physical book and how they smell. They make you feel good. However, there are disadvantages. Printed books may get damaged while you are traveling. Or even at home, accidents could happen. For example, you may spill water on printed books. That does severe damage.

On the other hand, eBooks are on your phones and other devices. That said, you can bring multiple eBooks anywhere without making your bag heavy. Also, eBooks are better protected from things that could damage physical books. If your phone breaks, you can transfer the SD card or install the eBook reading app on another device. You can also store the eBooks on Cloud to access them from multiple devices.
