How to Download Free Books on InfoBooks

No sign-up, no limits, 100% free.

At InfoBooks, we believe that access to books can change lives. That's why we offer thousands of free PDF books, with no sign-up and no download limits.

How does the download work?

Follow these three simple steps to download any book from our library.

1

Find your book

Browse our categories or use the search to find the book you're interested in. Click the download button.

2

Sometimes, a short ad

Your first download starts instantly. After that, a short ad shows up every now and then before the download starts: it's what lets us keep sharing free books.

3

Automatic download

The PDF file saves automatically to your device, in your downloads folder. That's it!

Why an ad?

InfoBooks is a completely free site. Ads are our only source of revenue and allow us to keep the site online, add new books, and guarantee a service with no sign-up or hidden fees.

Using an ad blocker?

To download, pause your blocker just on infobooks.org: every other site stays the same. It takes a few seconds, and then you download without limits. See how to do it.

How to turn off your blocker for InfoBooks

The change only applies to infobooks.org, so every other site stays the same. It takes a few seconds, and then you can download as many books as you want.

Don't know which blocker you have?

  • On a computer, look to the right of the address bar: each blocker has its own icon (a red shield, a white hand, the letters ABP or a green shield). If you don't see any, click the puzzle piece icon: that's where all your extensions live.
  • On a phone there are almost never extensions. The block usually comes from the browser (Brave, Samsung Internet, Opera, Edge) or from the connection (a VPN or Android's Private DNS).

Blocking extensions

They're installed in your computer's browser. They're the most common cause.

uBlock Origin Red shield

In Chrome, Edge, Brave and Opera (uBlock Origin Lite)

  1. Click the uBlock Origin icon (a red shield) next to the address bar. If you don't see it, look inside the puzzle piece icon, where all your extensions live.
  2. Drag the filtering mode slider all the way to the left, until it says no filtering. That turns it off only on infobooks.org.
  3. Go back to the book page, reload it and hit Download.

In Firefox

  1. Click the uBlock Origin icon (a red shield) next to the address bar.
  2. Click the big power button so it turns from blue to gray. That turns it off only on infobooks.org.

AdBlock White hand on a red background
  1. Click the AdBlock icon (a white hand on a red background) next to the address bar. If you don't see it, look inside the puzzle piece icon, where all your extensions live.
  2. Choose Pause on this site and then Always. With Once, it starts blocking again on your next visit.
  3. Go back to the book page, reload it and hit Download.
Adblock Plus Red ABP letters
  1. Click the Adblock Plus icon (the letters ABP on a red octagon). If you don't see it, look inside the puzzle piece icon, where all your extensions live.
  2. Under Block ads on, turn off the This website toggle (infobooks.org).
  3. Go back to the book page, reload it and hit Download.

  1. Look for your blocker's icon next to the address bar, or inside the puzzle piece icon where all your extensions live.

  3. If your antivirus has web protection (Avast, AVG, Kaspersky, Norton), check its ad blocking too.

Antivirus Avast, AVG, Kaspersky, Norton, ESET
  1. Open your antivirus (Avast, AVG, Kaspersky, Norton, ESET or Bitdefender) from the taskbar, the menu bar or your apps menu.
