Which Book 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 Something Else. PDFs sometimes display awkwardly on small screens, while some eBook formats are designed especially for reading on smaller screens. If you have a smart phone, PDA or special ebook reader device, then you should choose a format suitable for that device.
About the Different Formats PDF for Digital Editions 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 Digital Editions, especially for reading ebooks. Most recognized book publishers release ebooks in "copy-protected", encrypted form and PDF for DE 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 MobiPocket, ePub and MS reader) tend to lose page formatting when displayed on a computer screen.
ePub for Digital Editions Adobe Digital Editions has been developed to make it possible for you to read your favourite ebooks on computers as well as a wide variety of hand-held devices, phones and ebook reading devices. 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.
