Sometimes there are legal or contractual reasons that require the site owner to take all possible measures to prevent downloading the file. The most obvious one I can think of has already brought up. This option comes up even in Reader no matter what other security selections you have chosen. In our case, Adobe Acrobat was purchased solely to provide some degree of protection for their own format. It is hard to believe that Adobe will let you prevent printing, prevent editing, prevent even opening without a password or you can really go all out and use a certificate for your encryption.
Yet they have no options to prevent saving at any point, anywhere. There are probably programs that are actually sold just to remove the DRM from Adobe documents and even if not, the point was that the client specified that no downloads be allowed even by users who had access to the private site.
Therefore the need to prevent the download to start with is not so hard to understand. Unless I can find a way to prevent opening, saving etc for a Flash File. Next, is it possible to password protect a Flash file from opening when clicked on?
I am not sure if I could post the code here or whether it is acceptable to paste links either but a Google search for "Maximus right click" will take you to it. And it was one of several examples, it just happened to be the one I could implement the easiest and worked better than the others. Credit where credit is due. It seems to me that this is a place where there is an obvious need for a one-step packaged solution and usually "The Laws of Nature" take care of such an Imbalance in short order.
Yet my research has taken me through many years of posters all asking for the same thing. If I find it, and it works, I'm buying it. I wish I had skills as a programmer because I have some pretty good ideas of ways to implement such a product, unfortunately, I do not know how to put these ideas into practical use.
You could also control printing from javascript on the client side. Although we should agree that ultimately you cannot prevent some form of document capture specially through screen capture technology either through phone or computer , the goal is to prevent direct download of original document.
Some suggest you turn it into images, but this is not necessary. There is clearly a way, as several cloud services allow you to share pdf files, removing the download option, without converting the PDF to images a superior method because it retains important properties like word search. Personally, as a user of Outlook email, I use the cloud service it provides, OneDrive.
I am no expert on HTMl so cannot tell you exactly how it is done, but it might still provide you some insights. Here is the code for one particular PDF I shared without private information and other bits that seemed unnecessary to me :. I suggest to modify pdf.

You do know that anything you display to the user can be printed in some fashion or another If you serve it, they can find some way to use it. You can't stop a user from printing the screen. If you have information you want to display and you don't want it being printed physically, PDF isn't exactly the format of choice.
It's whole purpose is to be lovingly printed. In my business, the need for the PDF to not be downloaded is due to not wanting customers to be able to easily share downloaded materials with other people. I make worksheets, and if they are easy to share, the customer is more likely to email them to a friend. If sharing them is made more complicated, they are less likely to want to go to the trouble.
Not being able to download them without having advanced computer knowledge is good enough for me. Hope this sheds light on a need in the industry. Things like being able to get a screen shot, etc. Hope this helps. I i — Janet Giel-Romo. Add a comment. Active Oldest Votes. Legionar 7, 2 2 gold badges 36 36 silver badges 66 66 bronze badges.
Browsers' developer tools make it trivial to get at anything sent to the user, and you're not going to stop screen capture programs. Heck, the user could use their mobile phone to take pictures of the computer screen… — Donal Fellows. Right-click, view page source, get link of image under the transparent image. It's been in Firefox for as long as I can remember. I think I remember it existing in Mozilla Suite back before it got pared down into Firebird, which then became Firefox.
I consider that under 'one of the ways of getting at it that requires digging into the source. I say you can lock it down 'hard' but not 'make it secure. Ultimately you will need to: Create Images for each page Present those to the user on the web via your own interface html, flash etc Keep in mind flash wont work on Apple devices if that's required.
