At least one of these trust mechanisms must be employed in order for a script to be able to silently save a PDF to disk. The last one, digital signatures, is most useful for business documents, such as contracts that are passed back and forth between businesses or within an office. The first two are useful for workflow automation.

All three of these mechanisms provide a "Privileged Context" for code that requires trust. In Acrobat, there are three main trust mechanisms Actions ( batch sequences), trusted functions and digital signatures. They are not suitable for widely distributed files. Trust mechanisms are useful and appropriate in a small or closed environment, such as an office. They have to either explicitly save the file using the "File > Save…" menu item, or implicitly allow the save through a trust mechanism. It’s a security issue.Users would not be very happy if random PDFs downloaded from the internet could silently save themselves to disk. In the Acrobat/Reader environment, saving a PDF to disk is a protected operation. Let me start right off by saying that putting a script into a PDF form that saves the PDF can only be done under such restrictive circumstances that in most cases it is not practical. This is a common form feature requested in the forums. So far, I've only talked about using the save feature in the context of automating workflows, but what if you want to put a save button on a form? Placing a custom save button on a form As explained below, this restriction was mostly removed in version XI, making Reader a much more useful tool in Document Workflows. Saving in Reader is a little different since this functionality was traditionally off limits, except for specially "Enabled" documents. In fact, this is a feature that has been around for a long time, so everything discussed here is valid for old versions of Acrobat as well as Acrobat XI. Being able to save a file to disk is a critical activity for Acrobat workflow automation, and fortunately, there are a couple ways to do this from an Acrobat script. This article presents scripts for not only saving a PDF file to disk, but also for saving the PDF to different formats, such as an image file, MS Word, text and even HTML.
