PDF Drive

Best PDF book downloader PDF Drive

PDF Drive is a comprehensive search engine site to download free PDF books online. The book library covers a wide range of categories, including health, fiction, and technology. This PDF book downloader now has indexed more than 80 million free PDF books. This is a website that is worth spending your life exploring.

Different from other PDF searchers which are unable to read online, this site allows you to browse the full content using its “Preview” feature. There is no need to download the book to immerse yourself in the story.

One highlight of this PDF book downloader is that as a website for free PDF books, it doesn’t have many annoying ads. The advertisement only shows once when you first download a PDF book or textbook, then it won’t bother you anymore.

Library Genesis

Library Genesis is a popular PDF book downloader to download free PDF books online. This search engine focuses on science and technology but also provides free PDF books of other genres online. More importantly, for students who wonder where to get free PDF textbooks, this site is an ideal textbook PDF finder.

To locate your target book or textbook, it’s recommended to type in the specific title or author. The filters help you narrow the results by topics and fields. However, the user interface of this textbook PDF finder is a little 2000-ish and it needs time to get used to the way it searches. Moreover, it is impossible to browse for books you may like on this PDF book downloader. You need to enter the exact name to download PDF textbooks for free.


Best PDF book downloader Overdrive

OverDrive is one of the best PDF search engine sites to download books in PDF format. This PDF searcher not only collects free PDF books online but also audiobooks and magazines to meet your needs. As a comprehensive PDF book downloader, it collaborates with many public libraries across the world. Hence, the available free PDF books online span different types, genres, and languages, removing worries about legality.

This website for free PDF books acts the same as a physical library, which means you need a valid library card to “borrow” those books. As a result, signup is essential and the procedure to download PDF novels is more complex compared to downloading free PDF books from other PDF book downloaders.

In addition, OverDrive works with Sora, a student reading app offering access to textbooks from schools. This makes it a perfect textbook PDF finder. Students can download free PDF textbooks online for their classes.

PDF Search Engine

This is another powerful textbook PDF finder that can locate free textbooks online. Besides textbooks, it has a vast collection of fiction and non-fiction books such as magazines and novels in PDF format. The UI resembles Google search and functions fast to grasp your target eBooks.

However, this PDF book downloader doesn’t have any filter and is unable to browse for books. The over-intuitive user interface makes it difficult to index the textbook or eBook if you don’t know the exact book name.


Best PDF book downloader Manybooks

Manybooks is a dedicated PDF searcher to download free PDF books online. Each book is detailedly classified, covering fantasy, biography, non-fiction, and so on. In addition to the PDF format, this PDF book downloader also offers books in formats such as ePUB, Mobi, and AZW. If you have a Kindle, you can import the book to the device without converting PDF to Mobi or other eBook formats.

This website for free PDF books constantly updates its archive, allowing you to get a growing list of up-to-date free PDF books online. The filters let you browse the library by ratings, language, and genre. However, signup is required to download books in PDF format online.

PDFs are not easy to edit and hard to adjust while reading. If you like taking notes or writing down your thoughts, switching between your downloaded PDF books and the notebook might be quite troublesome. This problem can be soon resolved using a nifty PDF viewer and editor. Let’s get an overview of this PDF software and learn how it can help you to improve your reading efficiency.
