What technology is required to use my PDF eBook?

PDF eBooks are readable on most computers and handheld devices using Adobe Reader. Some operating systems and browsers are also able to read PDF files without Adobe Reader using built-in tools. PDF eBooks are more similar to printed books than ePub and Mobi files are: the text of the book is "set" in a fixed layout on the page. This makes PDF a good format for larger screens, such as computers or tablets, but less ideal for smaller screens, such as smartphones or eReaders.

eReader devices are hardware devices (computers, smart phones, iPads, etc.) that function primarily to display PDF eBooks.

eReader software is a program that allows the reading of PDF eBooks on additional hardware devices, such as personal computers or mobile phones. For more information see our eReader Hardware and Software Guide.
