How to view pdf without download option?

Question

PDF

Good afternoon!

How to place a pdf on the site without the possibility of downloading?
Tried like this

<iframe src="http://www.RealAdmin.ru/assets/templates/main/files/Instruction.pdf" width="700" height="400"></iframe>

but there is a button "download"

Tried through google dox

<iframe src="https://docs.google.com/viewer?url=http://www.RealAdmin.ru/assets/templates/main/files/Instruction.pdf&embedded=true"
                style="width: 600px; height: 600px;" frameborder="0">Ваш браузер не поддерживает фреймы</iframe>

but there is a button "in a new window", when clicked, it will go to the Google site. and here you can already download the file and save it on google drive.

Is it possible to view only - without explicit buttons for downloading the file?
