EPUB 3: A Format for Every Kind of eBook

EPUB 3, developed by the IDPF (International Digital Publishing Forum) is an excellent format for eBooks. It includes support for much of what we know as HTML-5 on the Web. That includes JavaScript, HTML-5 markup, CSS3, and much more.

 

It opens the door to get interactive with eBooks and improves upon EPUB 2. At Wundr, we’ve invested in this format as our eBook desktop publishing program, Playwrite, is native to EPUB 3. Not all eBook Readers fully support all of the features and functionality of EPUB 3, but support and improvements have been forthcoming.

 

EPUB vs. PDF

 

Many people inquire about the benefits of EPUB vs. PDF. The main difference between the two formats is that EPUB is meant to reflow and PDF isn’t. Where one flows like water, the other is hopelessly fixed. With PDF, it’s effectively like a fixed piece of paper that is showing the reader close to an exact rendition of what cotent looks like printed on a piece of standard size paper.

 

With EPUB, its essence is to flow. That is, it orients itself across multiple pages and multiple screen sizes. This is much different than PDF. A user will have difficulty interacting with content on say an iPhone reading a PDF document because he will have to pinch and zoom to properly see and read content. The EPUB document will present content to the user without the need for him to pinch and zoom. Fonts will be the right size, images will have scaled to fit the screen, and so forth.

 

When the EPUB format is combined with the latest in responsive Web design, the benefits are even more pronounced. That’s what we’ve tapped into here at Wundr, by combining the best eBook format (EPUB) with the latest in responsive Web design.
