As publishing moves in a digital direction, ebook formats are becoming increasingly popular. It’s important to note that not all ebook formats are created equally. Each device is built a specific way and each device has its specific technical requirements for displaying an ebook file. By having some basic knowledge about the different ebook formats, you will have a better understanding of which format is best for you and your individual needs. 

 

Types of Ebook Formats

Knowing at least the basics of ebooks formats will allow you to choose which format you will be comfortable with. There are multiple formats available but ChatEbooks lists down some of the most popular ebook formats for you to choose from.

 

PDF

PDF is one of the oldest ebook formats. It is a popular ebook format that is recognized by Adobe Acrobat Reader. PDF stands for “portable document format”. This format adds support for features such as compression, passwords, and semantic structures. PDF documents can be easily viewed and printed by users on various platforms, making this format very popular on the worldwide web. PDF files are supported by nearly all modern ebook readers, tablets, and smartphones. It should be noted that while PDFs can be transferred to an ereader, the PDF files cannot be purchased through ebook stores such as Amazon. Because this ebook format does not have the same functionality as other eBook formats, PDFs are not considered a true “ebook”.

EPUB

EPUB is considered to be the “universal” ebook format. It is supported by the largest number of e-readers and is widely supported across almost every platform. EPUB is supported by iPad, Nook, Kobo Reader, and most other ereading devices. The only notable ereader that lacks support for the EPUB format is the Amazon Kindle. This format is also supported by several software readers as well. These programs give people the ability to read ebooks on their laptops or computers, instead of purchasing a separate device. EPUB format is an open standard format, meaning it is free and publicly available although there are some specific rules users must follow to use it. 

MOBI

Another well known ebook format is Mobi. This is a cross platform that was bought by Amazon. Mobi can only be used exclusively by the Amazon Kindle ereader. Various Kindle apps, such as Kindle for PC, Kindle for Mac, and Kindle for iPad are also supported by Mobi. This eBook format is based on the Open ebook standard. The reader has a full screen mode for reading. This also allows support for many PDAs, communicators, and smartphones. 

AZW

AZW is an Amazon format that is used exclusively by the Amazon Kindle. Basically, it is a Mobi format that uses a high compression option. AZW files can be opened on smartphones (iPhone, Andriod, and Blackberry), computers, and tablets. 

EREADER

eReader is an ebook format that allows users to view Palm Digital Media electronic books that use the pdf by several Palm applications. This reader shows pages one at a time, just as a paper book does. This ebook format supports iPhone, Palm OS, Android, Symbian, Blackberry, Windows Mobile Pocket PC/Smartphone, Windows desktop, and Macintosh. 

Multiple formats can cause confusion. By gaining a better understanding of all of the popular ebook formats out there, you should be able to distinguish the difference between each one and know the devices that support each type.
