revoke individual user access to single, multiple, or all documents
revoke access automatically after a number of views and/or prints
Add dynamic watermarks to viewed and or printed pages. Dynamic variables (date/time, user name, company name, email address) are replaced with actual user and system data when the protected PDF document is displayed and/or printed.
You only have to protect a document once in order to customize it for multiple users.
Disabling ‘save’ and ‘save as’ options in a PDF viewer application is just one of many methods you can use to prevent a PDF from being saved, copied, and shared. Stopping PDF printing, locking PDFs to devices and locations, and watermarking documents are also essential in controlling document use.
Most applications allow you to open a document and save a copy of it to another location on disk. This is no different from copying a file directly in Windows File Explorer or a similar file browser application.
When a document is opened by an application (be that Word, Acrobat, or a browser) a temporary file is created and saved to disk. Any changes made are then applied to the temporary file which may either be saved as a new document or overwrite the existing document.
Temporary browser cache files
So to prevent PDF saving from taking place, you need to build a special application that does not have these capabilities, rather than trying to rely on third-party add-ons to remove existing functionality.
Some techniques, such as plug-ins, attempt to disable the save and print option in PDF file viewers by altering code in the application. This is not a good approach because anything being disabled by one plug-in may be enabled by another. Additionally, because all the functionality is still there, a hacker is not prevented from connecting to it.
For management control systems that rely on access control mechanisms (non- DRM protected files), you need to prevent PDF saving so that files cannot be moved to different locations, such as memory sticks or servers, or network drives, where the access controls may be very different.
The simplest way to disable saving is to not have the code to do that present at all. The same goes for saving PDF files, which means not using one of the standard PDF viewers. Locklizard Safeguard viewers prevent the saving of PDF files using this approach since it is impossible to use code that is not there.
Will disabling the Save and Save As option in PDF viewers give you enough control?
You need to prevent access to the Save and Save As commands if you don’t want uncontrolled copies of documents being distributed. They represent the simplest way to prevent a document from being copied that has been opened in an application and should be a high priority.
A password ‘protected’ PDF file being saved in Adobe Acrobat
However, it is important to note that when you prevent a PDF from being saved you are not stopping people from making copies of the original file(s) by using the copy command in Windows File Explorer. Documents also need to be protected (using encryption), have user licensing (locking documents to devices and locations) and DRM controls (stopping copying/pasting, printing, watermarking, etc.). Only then can you prevent someone from copying a document and sharing it with unauthorized users. If documents are not adequately protected from copying and sharing, then preventing just PDF saving is not going to achieve much.
By using adequate document protection, you can prevent Save and prevent Save As so that a copy cannot be made without the encryption, licensing and DRM controls being embedded in the document. Otherwise, it might be changed to a format that may not apply this protection (i.e. saving the document as a text file, picture file or a different unprotected document format). There are other ways of copying the contents of a document, but if you can prevent the PDF from being saved then you will have stopped the simplest and most effective way of making copies of documents.
In short, you do need to disable the save and print option in PDF viewers to stop unauthorized sharing. However, you also need to prevent copy-paste and screen grabbing, provide strong encryption, and allow documents to be restricted to devices and locations. All of these aspects must work flawlessly for document security to be maintained.
Disable PDF save and print in the browser
A secure PDF in Locklizard web viewer
If you want to disable PDF saving and printing in a browser environment, then you need to make sure that content is not cached to disk but served only from memory. You can only do this if you run an application in the browser. Safeguard Web Viewer uses this method to prevent Save and Save As of protected PDF files to unprotected formats.
Preventing document printing to unprotected formats
Another pitfall that allows documents to be copied is letting users print them. Printed documents can be scanned in and saved back to PDF (with a bit of OCR software you can convert to text rather than images). It is important to also address the following if printing is allowed:
stopping printing to file drivers (PDF, XPS, etc.). Users, therefore, have to make the extra step of scanning printed documents if they want to make an electronic copy.
applying dynamic watermarks to identify users. Users are less likely to share documents if their name is plastered all over it.
limiting the number of high quality print copies allowed or allowing only degraded printing.
tracking use so you can see when and where documents were printed.
Safeguard PDF Security uses all of the above methods if printing is allowed, and enables you to stop users from printing documents altogether.

How can I prevent a PDF from being saved/how do I stop someone from saving a PDF?
To prevent a PDF from being saved, you need to employ a combination of strong encryption, a licensing system, DRM controls, and a secure viewer application that does not have the function to save documents. You must also make best efforts to prevent copying via screenshotting or printing, by blocking first and third-party screen grabbers, limiting printing, and adding dynamic, identifying watermarks.
How do I disable the save as option in Adobe Acrobat DC?
There’s no good way to disable the save as option in Acrobat. Technically, you can apply permissions to prevent editing, but this only greys out the save option, not save as. Also, the permissions can be easily removed by free online tools or other simple methods.
How do you stop people from printing your PDF files?
By avoiding solutions like Adobe Acrobat and utilizing a fully-fledged PDF DRM solution instead. Locklizard Safeguard allows you to disable printing of the document in the viewer application in a way that cannot be bypassed. It also grants publishers the option to restrict the number of prints, only allow printing in black and white, and more.
How do I download a PDF even when the website doesn’t allow it?
Can you disable PDF save and print in the browser?
Is it possible to make a PDF non-downloadable?
Technically, yes. You handcraft an application to receive information from a server one line at a time when printing or displaying text. This will minimize caching, which will make it quite difficult to download a document when the printing and saving of PDF files is also disabled.
However, displaying a document without caching can cause serious performance problems, especially when you run into images or more complex font rendering. In all likelihood, users will do whatever they can to avoid using your application, as it will be frustrating.
Another option is to convert the PDF to images and display those to users instead. The downside with this approach is that image rendering is slow, especially on mobile devices. Also hyperlinks will no longer work.
How can I sell a PDF and prevent saving?
