But first we'll look at the differences between the two folders. But while the Acrobat/Reader applications are similar, the file systems on each platform are very different, and this is where the details of stamp file installation get a little complicated (on both platforms). One other similarity is that the user folder doesn't exist when Acrobat/Reader is first installed.

And in both, a stamp file is installed by copying it into one of two file system folders, the user folder or the app folder. They even look the same on both platforms. Both have the same menus and tool buttons, so the Stamp and Commenting tools are accessed in the same way. MacintoshĪcrobat Professional and Acrobat Reader are nearly identical on both platforms. These steps are similar, but different for the Macintosh and Windows platforms. It's not difficult, but there are a few steps you need to follow. But if you acquired a stamp file from somewhere else, or want to share a stamp you've created, then it gets more complicated. If you are making your own static stamp with the Acrobat stamp tools, then Acrobat does the installation for you. To add a new stamp to Acrobat's list of stamps, that stamp file has to be installed into Acrobat.

In Adobe Acrobat/Reader and most other PDF viewers, that custom image is a page in a special kind of PDF file, called a stamp file. And like a rubber stamp, a PDF stamp has a custom graphic/image. A PDF Stamp is a type of PDF markup (comment), just like a rubber ink stamp for paper.
