At InfoBooks, we believe that access to books can change lives. That’s why we offer free books in PDF, with no registration and no download limits.
To keep the site running (servers, bandwidth, and continuous improvements) we’ve introduced a simple and transparent system.
Before each download, we ask you to watch a short ad. This small action helps us continue sharing thousands of free books with readers around the world.
How does downloading free books work?
The process is simple and always free:
Step by step
- Click the download button of the book you want.
- One of the following will happen:
- If you use an ad blocker, you’ll see a message asking you to disable it to continue.
- If you don’t use an ad blocker, a popup will ask you to watch a short ad.
- After watching the ad, the download starts automatically from our CDN.
That’s it.
Why do I need to watch an ad before downloading?
Ads help us cover the basic costs of the project and keep InfoBooks as a free and open library.
- We don’t charge for books
- We don’t require registration
- We don’t limit downloads
Watching an ad that lasts only a few seconds allows us to maintain this model and continue offering free book downloads to readers everywhere.
What if I use an ad blocker?
If you have an ad blocker enabled, you’ll see a message asking you to disable it in order to download the file.
We kindly ask you to turn it off to continue. Once disabled, you’ll be able to download all free PDF books without any issues.
Unlimited downloads, no registration
Just to be clear:
- You can download as many books as you want
- No account is required
- We don’t collect personal data
- We don’t track individual users
We only ask that you watch one ad before each download.
