As the world goes digital, publishers can no longer afford their customers PDF files as eBooks, given that the readers expect to access premium content online. It is little wonder then that publishers are taking the ePUB3 conversion route to digital publishing for their eBooks. The ePUB format is easily accessible across a range of devices including mobile, tablets, notebooks and computers.
The ePUB standard is developed and maintained by the International Digital Publishing Forum (IDPF) and is endorsed by the Book Industry Study. ePUB3 is the latest version of ePUB, based on the latest HTML5 standard. The ePUB3 format is dynamic in nature and is supported by emerging technologies such as HTML5 and CSS3. Since it is an HTML5 format, text can be hyperlinked to refer to both internal sections of the eBook and external reference links, for more information on the subject. ePUB3 also incorporates SEO capabilities enabling online readers to search content based on keywords.
EPUB3 allows for two types of layouts: Fixed layout and reflowable layout. Here’s a closer look at both the layouts:
1. Fixed Layout ePUB:
A fixed-layout basically defines individual pages, or in other words, the size of the “page” in pixels. The page usually contains many images precisely positioned relative to the text. In this layout, you cannot change the font size. The fixed layout ePUB format, in other words, is an exact rendition of a printed page. On a small screen, you will have to zoom and scroll the page, vertically and horizontally to read the text. The fixed layout format works well for graphic-heavy publications such as photo books, magazines, and comics, or if you want your text to be multi-column
2. Reflowable ePUB:
This format is more suited for publications that have a simple, one-column layout and is text-heavy with small images that can be embedded between paragraphs. This layout is accepted by most devices, given that the content ‘flows’ to fit the screen size. However, reflowable format limits the power of authors who have little control over how their content will be displayed. Besides, they are also somewhat restricted in the use of fonts.

Search on the Internet for a suitable ePub3 conversion or digital publishing software or platform to convert PDF files into the fixed-layout ePUB format.

You can, however, select similar fonts or from a URL.
