Download free books for Kindle – sources and tips (1)

Looking for free Kindle books that you can download to your computer, Kindle e-reader or Kindle app? Here are the legal online sources, plus key usage tips.

You can find Kindle compatible books not only on Amazon. Thousands of these books are free of charge, and you can download them to your Kindle completely legally from other online websites.

In the post below, we will list not only the sites with public domain books that you can use to collect free Kindle books, but also tips that will let you better manage and enjoy these sideloaded docs on your Kindle e-reader or in a Kindle application.

In general, there are up to 100,000 free classic books that are available completely for free for your Kindle, and the best place to get them is actually not the Kindle Store (although you can find here some of the classics, as well).

There are a couple of things to keep in mind to make adding own books to Kindle easier and quicker, so let’s start with the tips.

Download free Kindle books – tips

Pick up the right format – epub

For a long time, to add your own book to the Kindle from another online source, you had to pick up a mobi format, while all other ebook stores use epub.

It changed in August 2022. Since that time, the compatible Kindle format is epub. The mobi format is not supported any longer.

In other words, if you want to download any book from the sites listed in the second part of this overview, please make sure to pick up epub, not mobi.

You won’t add epub files with DRM

If you were using another ebook store, such as Kobo, Barnes & Noble Nook, or Google Play Books, may assume that – as these sites use epub format by default – you will be able to quickly transfer these books to the Kindle.

No, you won’t be able to add epub files from other stores to Kindle. These files, even if you have downloaded the free books from these stores, are in a vast majority protected with some kind of DRM (Digital Rights Management).

An epub file with DRM won’t be added to your Kindle library, because Amazon won’t be able to open it.

Enjoy free Kindle books in the Kindle app

You can start collecting the library of Kindle books even before buying a Kindle e-reader.

There are many free Kindle apps available for computers and smartphones/tablets, including Mac, Windows, iOS, Android, and BlackBerry operating systems.

The key to Kindle ecosystem is your Amazon account. All ebooks you add to your Kindle virtual library will be synced across devices and apps registered with that account.

Not only the latest readlocation, but also bookmarks and notes will be synced, and this is one of the most important benefits ebooks can give.

How to add own books to Kindle

There are a couple of ways you can add own books to the Kindle e-reader or tablet/smartphone app:

1. The most popular way is to send a file to the email address associated with your device. If you buy a Kindle or download a Kindle app, first thing to do is to sign in with your Amazon account. Since that time this device/app is given a special email address to which you can send the files. You can find it in the Settings section.

2. You can also use a Send to Kindle application. It’s available for Mac and Windows, but you can also get it for Chrome and Firefox browsers. While the desktop version lets you add files stored on a computer disc, the browser extension helps add web content.

3. If you use a cloud storage service like Dropbox, you can upload the file to it from your computer, and use a Dropbox application on your tablet or phone to download the file to Kindle app.

4. If you have a Kindle e-reader, connect Kindle to your computer and drag the files into Documents folder inside the Kindle disc image.

5. If you have a Kindle app installed on your smartphone or tablet, you should be also able to add the file if you tap on it. A list of applications capable of opening it should be displayed, and if the file is in mobi format, you should see a Kindle app.

How to manage own ebooks in the Kindle library

The books you have added yourself to your Kindle library are separated from the ones you have purchased and downloaded from the Kindle Store.

  • Books from the Kindle Store are called “Books”– these are all the titles that you purchased or downloaded for free from the Kindle store, including free samples.
  • Books from other sources are called “Docs”– these are the files that you have added to Kindle by sending them via email, using Send to Kindle extension, or sideloading from your computer.

The two sections can be seen in filter options in both Kindle e-readers and Kindle apps for iPad/iOS and Android. Your own books are displayed with a blank page until you open them and the original cover image (if it exists) is properly rendered.

The Books vs. Docs split is even deeper on Amazon Fire tablet. Native Kindle books can be managed using “Books” app. However, if you add your own books, you should look for them in the “Docs” app, not “Books.”

Please note that you won’t be able to read your sideloaded books in the online Kindle reader at Also, any highlights and notes you have made to sideloaded books will not show up here.

You can get Jane Austen’s book for free from Project Gutenberg, and find out that the same title costs one or two dollars in Amazon’s Kindle Store.

A good thing about books from Project Gutenberg is that if the original print edition had illustrations, you will be also able to get them in the ebook version.
