On the Amazon website, you can navigate to the Free Kindle eBooks section to find free books. You'll find books organized into categories that you can browse through at your leisure.
Many of these books are classics in the public domain, and feature similar cover art. They'll have a button that says "Buy for Free" on their individual payment pages.
You can also find many of these same titles in the Cheap Reads section of the store. In addition to free books, this section also includes Kindle Unlimited and Prime Reading books, which you can read more about in their sections below.
Finally, you can simply search for "free kindle books" on Amazon's website. You'll be shown a host of free books, many of which are temporarily on sale.
To find these books on an actual Kindle device, unlock your screen and tap the shopping cart to access the store.
On the homepage alone you'll find the Deals category, along with Kindle Unlimited and Prime Reading options. The Deals page organizes books into daily, monthly, and exclusive deals where you can often find free or reduced-price books.
You can also manually type "Free" in the search bar at the top, which will automatically populate search results such as "Free Kindle Books for Kids."
This list will include free books and those that fall under the Prime and Unlimited subscriptions as well.
Tap on any book to open it and follow the steps to download it for free.
