Ebook Formats


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.

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. PDF is not particularly well suited for smaller screens like smartphones and eReaders.


The MobiPocket format is owned by Amazon and is compatible with all the Kindle reader devices and Kindle reader software. You might see the format referred to as the Kindle format as well, but it is functionally the same.


ePub is a popular format and is used with almost every non-Kindle reader. The format makes 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.
