How to convert a PDF to ePUB

There’s some debate as to whether PDF files or ePUBs are easier to read. Some say that PDFs produce less eye strain and provide a more aesthetically pleasing experience because PDFs are restricted to showing pages as they were originally saved, omitting adjustments for images, font size, and other page aspects. On the other hand, some prefer ePUB’s flexibility. ePUBs allow text size to adjust to the dimensions of your tablet or eReader’s screen, while retaining the original formatting and layout.

Whatever your preference, some devices, like iPads, offer native support for ePUBs, but none for PDFs. Also, there are a number of situations where ePUBs are the preferred file format. With that in mind, we offer the following guide on how to convert PDFs to ePUBs.
