Google Books is service from Google which provides you with millions of books online, available for purchase as well as reading. The service comes with tons of free books which are readily available for reading. While the service is really awesome, it does not provide any means to download the free books to desktop. Google Books Downloader is a freeware tool for Windows which can help you download the books from Google.
You just need to specify the book URL collected from Google Books into the app. You can download as JPEG or PDF file based on your requirement. You can specify the location where you want to download it.
Please note that the app supports only the books marked as “full view”.
