Formats Supported by the Amazon Kindle E-Reader

Formats Supported by the Amazon Kindle E-Reader

If you have a Kindle, you have probably wondered what kind of documents it can reproduce . Maybe you have a Word document, or any other extension, and you want to read it on your Amazon device, but you don’t know if it is possible. Or you have not been able to see a specific book directly. The Amazon platform has its own format for eBooks and is compatible with different ones.

The first generations of Amazon e-Readers were compatible only with the native AZW format and with the MOBI and PDF extensions. Probably with the intention of implementing it as a standard the one expressly designed by the brand (AZW).

The problem that was generated is that the owners of an e-book of the Amazon brand needed other devices to read documents in other popular formats such as EPUB or image extensions such as JPEG or PNG, for example. Having to go to conversion programs was a solution, but it is still a waste of time. This is why the last generations already support a series of popular documents that allow a greater range of possibilities .

AZW, Amazon native format

This is the original format developed by Amazon for the distribution of its e-books. It is a protected format to prevent the distribution of files in an unauthorized way. Documents edited in the AZW extension are protected with DRM, which is a control system that makes it impossible to copy the file and distribute it freely. In the same way, it is a format compatible with the most used platforms such as Windows, macOS, Android and iOS, as well as the readers designed by Amazon.

They are files that allow you to work with documents because we can add annotations , include bookmarks , underline and other typical actions of electronic books because they contain, in addition to text , other objects such as graphics , tables and images .

The AZW format has two variants: KF7 and KF8 . The first is the startup version, which is basically a MOBI file, purchased from the Mobipocket company. DRM protection is unique to Amazon, so they remain protected files that cannot be played on any MOBI-compatible device. The enhanced version of the format is KF8, which includes a Palm database structure and support for HTML5-based text and CSS3 style sheets. It is a format with more possibilities but that maintains a copy of the content in MOBI format so that it can be read by older devices. This increases the weight of the files as well.

Other supported formats

The different generations have evolved and are increasingly compatible with a greater number of formats . Since these are files that may not require as frequent an update as can happen with smartphones, you may have a relatively old model that is not as compatible as you would like. For these cases we propose a solution for manual file conversion, for this, the formats natively compatible with Amazon e-book models are:

Read EPUB

The EPUB format is the file par excellence when it comes to downloading electronic books or sharing them with other users. It is the most widely used standard and the Amazon Kindle is not compatible with this type of document. The acronym comes from Electronic Publication (electronic publication) and is a very versatile type of file that allows a dynamic page adjustment so that it can be used with all types of devices. In addition, it allows adding a DRM security layer to prevent illegal copying of books.

Amazon devices do not support the EPUB format. It is probably a way to safeguard the original content of the electronic books distributed by the platform and avoid eBook piracy. That is why the only solution to reproduce e-book content in this format on Amazon devices is by converting the file to another compatible format from those discussed above. For this we can use a free converter such as Caliber and then upload the files to the Library directly through the Kindle App or as attachments by email.

Send and convert books

Although the personal documents tool allows you to upload different types of files to reproduce them in Kindle format, if what you need is to reproduce documents in EPUB format we will have to convert it with Calibre.

Convert formats with Calibre

You may have already noticed that one of the most popular files for e-book publishing, which is the EPUB format , does not appear as compatible on any of the models. In order to use files of this type, or other different ones, that are not compatible with the Amazon e-Reader, we can do a format conversion with Calibre.

Calibre is an electronic book manager that allows you to make conversions between different eBook files.

My Kindle Library

On your device to read electronic books, you store the books you acquire through the platform, depending on the storage capacity of your device, you can include many titles without having to delete any in My library .

In addition to the titles that you download from the Amazon website, either with titles included in the Unlimited service or with the e-book versions that you buy from Amazon, you can also send other personal documents to your device to make them easier to read without the need to print them or have to use other devices such as the computer itself, the tablet or the smartphone. After all, spending long periods of time in front of screens of this type increases eyestrain and is not recommended for reading books.

This tool allows us to upload our personal documents edited in other extensions than the application account to be able to read them in Kindle format. The personal account allows us different ways to synchronize personal content on our profile. Generate an email, which will be the address to send the documents that will be synchronized with your Library, or you can also use the official Google Chrome extension designed by Amazon, the application for Windows , for macOS or for Android devices .
