Digital Formats for ebooks

ePUB2 OR ePUB3? 

All conversions produced by EBB conform to the ePUB3 standard; these can be validated by the ePUB checker found at http://validator.idpf.org/ 

Reflowable ePUB

This is the most prevalent ePUB format. It gives you an ebook legible on all sizes and types of screens—from the small cell phone screen to a large desktop reader.  The reflowable format does not support:

•    Full-bleed images
•    Text placed over images
•    Multiple columns of text (text in reflowable ebooks must be in full-width paragraphs)

Fixed Layout ePUB

These are HTML-based eBook files that are usually designed to match the layout of a print book. They work best for textbooks, technical or scholarly works, illustrated children's books, coffee-table books, comic books, comic strips, and magazine-style layouts. Features:

•    More control over page layout because they are coded to each specific device.
•    Images can spread across the entire page
•    The ebook text can be placed over images
•    Text can be arranged in multiple columns within a page
