Question: what is the difference between an epub ebook and a pdf ebook?
Answer: A PDF document is a digital paper, plain and simple. Whereas an ePUB file is like a website. ... And if you do not want to present your eBook in a reflowable format, ePUB also gives you the option to create fixed layout eBooks. A fixed ePUB format, just like a PDF, does not change its alignment as per the screen sizes.
