I don't want the browser to download when the user clicks. I do not whether there is a solution on VeryPDF? Then the viewer only can read PDF but they can not download it. The most important is that this software is totally free if you do not need to show PDF online more than 24 hours.

Thanks for your message, you can upload and view your PDF and other documents online from this web page, this can be done easily,. Also, it is prefered that user cannot print screen. Okay, I take back what I commented earlier. Just talked to one of the senior guys in my shop and he said it is possible to lock it down hard. What this will do is that if they right click on the 'image' to save it, they will be saving the transparent image instead. And since the image 'overrides' the iFrame, any attempt to use print screen should be shielded by the image, and they should only be able to snapshot the image that doesn't actually exist.
That leaves only one or two ways to get at the file Still not totally secure, but protected from your average user. A print screen will allow someone to recreate the low res image you present, and in this case you could add a watermark to the image.
That is not possible. Reading is downloading. When a user is reading a file, browser is downloading that file to temp. Tick Both check boxes. After copy embed link and paste it to your src. No download and Save drive option is not allowed. Alternative: You can create annotations that are only visible when printing. Creating a video with QuickTime's screen capture or anything similar kind of defeats all the effort to protect your document file from being copied.
You would have to be able stop the user running a program that can access the buffers in the GPU to prevent them grabbing a screen shot. Anything displayed on the screen can be captured. This will also be completely breakable for an extremely determined pserson. The last option is to send printed documents in the post. The old fashioned way using a good courier service.
Costs go up, time delays are inevitble - but you get exactly what you are after. A solution is not without its costs. I wish I had an answer but I only have Part of one. And I cannot take credit for it but the way to get it is below. This is a more serious issue than it is being given credit for from the sound of the replies. Everyone is automatically assuming that the content that needs protection is for public consumption.
This is not always the case. 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. Stack Overflow for Teams — Collaborate and share knowledge with a private group. Create a free Team What is Teams? Collectives on Stack Overflow. Learn more.
