We formerly offered Mobipocket (or MOBI) files as well, as that was for many years the only suitable format for Kindle devices and apps. In addition, captions, sidebars, and other complex visual elements may reflow oddly, and we have no control over that. Graphics in our books remain at a fixed size, regardless of your font size or other settings. Page numbers in EPUB are variable, so they won’t correspond to page numbers in the PDF format. This makes EPUB an ideal choice for reading on small-screen devices, but some people prefer it even on larger screens because it offers more control over the display than PDF and can require less scrolling. EPUB: EPUB is a “reflowable” format, meaning that you can change the font, size, or screen orientation and the text will reflow to fill your screen accordingly.On the other hand, PDF is generally not the best choice for devices with small screens, because zooming in far enough to be able to read the text may also mean you’re unable to see an entire line without a lot of tedious swiping. That makes it an ideal choice for reading on a Mac or PC, or an iPad (or other tablet) with a medium-to-large screen it’s also the right format to use if you plan to print any of our ebooks yourself.

PDF uses a page-based layout, which means page numbers are fixed, and each page always shows the same contents, regardless of how far you zoom in or out. PDF: This format has carefully chosen fonts, spacing, and other visual aspects to provide an excellent onscreen reading experience.This page helps you understand the options and transfer our books to the places where you want them to be. Which format(s) you choose depends partly on which device you plan to read it on, partly on which app you prefer to use, and partly on personal preference. You can download any or all of these, and can read them on almost any device. All our books come in two downloadable ebook formats (PDF and EPUB) the PDF format is also available as a compressed Zip file.
