About the different formats
PDF for Digital Editions / Ebook Reader
This means that the ebook was originally a PDF and has been encrypted to protect the author from the risk of piracy.
PDF is the most popular document publishing format for general use. You're probably familiar with PDF – it's the file format that normally opens up in Adobe Reader or Adobe Acrobat. In order to give users a simpler and "cleaner", less cluttered reading interface, Adobe developed Adobe Digital Editions (ADE), especially for reading ebooks. Most recognized book publishers release ebooks in "copy-protected", encrypted form and 'PDF for Digital Editions' is a popular choice.
The great thing about viewing PDF ebooks is that they retain the original design of each page – so you see on your screen exactly what the book designer intended. Formats that are more suited to smaller screens (like EPUB) tend to lose page formatting when displayed on a computer screen.
EPUB for Digital Editions / Ebook Reader
The EPUB format is perfect for reading on smaller screens, because the lines of text 'reflow' and adjust to accommodate varying font sizes and screen sizes. The EPUB format suits books with lots of images like comics, graphic novels and recipe books. You can also get 'enhanced EPUBs' which means that they can have audio or video embedded in the ebook so you can listen/watch inside the Ebook Reader app without having to be redirected to an external internet browser or video player.
The Online Reader format was created by eBooks.com. It allows you to read the ebook online in the same web browser you used to purchase your ebook. Currently the Online Reader is based on the original PDF file of the ebook, so it displays in a very similar way to a PDF. For more information see Using Online Reader.
Because Adobe Digital Editions isn't available on some mobile devices, we developed our own Ebook Reader app. Ebook Reader is compatible with the same PDF and EPUB files used by ADE, but expands the number of devices that can make use of these formats (check the device guide). We also developed our Online Reader which expands the number of compatible devices even further still to almost any device with an internet browser.
Which ebook format is for me?
For a Computer, Choose PDF
If you only expect to read your ebook on a computer (not on a phone or special ebook device), then you should choose a PDF-based ebook. This is because PDFs display the pages of a book exactly as they were designed by the book publisher. In other words, a PDF will usually maintain the design integrity of the original printed book. With other formats, pages can look different – sometimes radically different – when displayed.
For a Hand-Held Device, Choose EPUB
PDFs sometimes display awkwardly on small screens, while some the EPUB format is designed especially for reading on smaller screens. If you have a smart phone, PDA or special ebook reader device, then you should choose EPUB.
Although we suggest different formats for different devices, it is worth noting that some books are only available in only one format. Even if it is not the recommended format for your device, this does not mean that you will not be able to read the book perfectly well! Also the Online Reader is always another option.
