As electronic books are becoming increasingly popular, there’s often a discussion about which format is better.

In this article, we will look at the ePub vs PDF debate. Understanding the strengths and limitations of each format is crucial for authors, publishers, and readers alike. This article explores the nuances of both.

What is ePub?

The ePub format is easy to spot with its .epub extension. It stands for electronic publication. Most often, this format is used for eBook storage.

This format is designed to be flexible and can adapt to various screen sizes, making it popular for e-readers, tablets, and smartphones. ePub files can contain text, images, and even multimedia elements. They support features like bookmarks, annotations, and text-to-speech functionality.

For these reasons, most e-reader devices support ePub files. This format allows for a more dynamic reading experience.
