Find and Download Free Books for Kindle

While most eBooks available on the Amazon Kindle store are paid, here are some simple ways by which you can find and download free Kindle books for your reading pleasure.

Project Gutenberg, Open Library, Google Books, ManyBooks and FeedBooks

are some popular websites that offer a large collection of classics and public domain (copyright expired) books in standard formats like MOBI that you can easily transfer to your Kindle over USB or Wi-Fi.

Google Books are available in ePUB format which is incompatible with the Kindle but you can use the free Calibre software to easily convert Google ebooks from .epub to .mobi, a format that Kindle can understand. Calibre does not however support conversion of DRM protected ePUB files to Kindle format.

Also, the Internet Archive website mirrors the free eBooks that have been scanned and digitized by the Google Books program and here they also offer the same title in MOBI format that you can read on your Kindle without conversion.

Kindle eBook Pricing for International users

If the price of a Kindle book is mentioned as $0.00 on the Amazon Store, it may sometimes show up as $2.00 if the country associated with your Kindle account is not United States. This happens because Amazon charges a $2 roaming fee for “international downloads”.

If that’s the case, you can either temporarily change your Kindle country to US or transfer via computer and you may not be charged that extra $2 Whispernet fees.

If you don’t have the Kindle device (i.e., the hardware), you can still download any of these Kindle books and read them in your web browser (read.amazon.com) without having to install any software. Amazon also offers reading apps for your Windows PC, Mac, Android, iOS, etc. so you can enjoy your favorite books on your desktop computer, tablet or mobile phone without having to buy the Kindle Reader.
