Several years ago, I found an ebook online that used the EPUB format when I got my first Kindle. I wanted to download it, but I first needed to verify if Kindle supported it. It ended up that it didn’t support it, but it was possible to convert it to Amazon’s MOBI format. I was curious to know what other formats Kindle supported, so I researched all of the ebook formats that Kindle natively supports. Here are all of the file formats you can use on a Kindle.
Supported Kindle Formats
|File Format||Filename Extension|
|Amazon AZW ebook||.azw|
|Amazon MOBI ebook||.mobi|
|Unprotected PRC ebook||.prc|
|Compressed PostScript file||.psz|
|Microsoft Word document||.doc, .docx|
|Rich Text Format||.rtf|
|HTML page||.htm, .html|
|JPEG image||.jpg, .jpeg|
If you have an ebook format that Kindle doesn’t support, you can usually convert it to a compatible format as long as it’s not protected with digital rights management (DRM). For example, you can convert EPUB to AZW using Kindle Create or Calibre.
How families can manage their ebooks with multiple Kindles and devices
People who read books on Kindle naturally tend to buy most of their ebooks from Amazon.com. They also get handed down to other family members, and before you know it, there are multiple Kindles within a single household. Fortunately, Amazon makes it easy to manage digital content for the entire family.
Amazon provides a feature called Family Library. It allows books to be shared between two adult accounts, and children can be added as child profiles as part of an adult’s account. The ‘Manage Your Household’ page is located at amazon.com/myh/manage.
