Solution 1Recommended

Manually Transfer Stamp Files to the Acrobat DC Directory

You can restore your custom stamps by locating the stamp files in your old Acrobat library folder and copying them to the new Acrobat DC stamps folder.

Acrobat stores custom stamps as background PDF files hidden inside your Mac's user library. Since the upgrade process does not always migrate these files automatically, you must manually copy them from the legacy application folder to the current one.

1
Open the macOS Library Folder

Open Finder, click 'Go' in the top menu bar, select 'Go to Folder...', and type '~/Library/Application Support/Adobe/Acrobat/'. Press Enter.

2
Locate the Old Stamps

Navigate into the '9.0_x86' folder (or your previous Acrobat version's folder) and open the 'Stamps' directory. You will see PDF files representing your custom stamps.

3
Copy the Stamp Files

Highlight all the PDF files in the old 'Stamps' folder, right-click, and select 'Copy'.

4
Paste into the Acrobat DC Directory

Navigate back to the main Acrobat folder and open the 'DC' folder, then open 'Stamps'. Right-click inside this folder and select 'Paste Item' to transfer your custom stamps.

5
Restart Acrobat

Launch Adobe Acrobat Pro DC. Open the Stamps palette to verify that your imported custom stamps are now available for use.

Hidden User Library: If you cannot find the Library folder under your username, it may be hidden by macOS. You can temporarily reveal it by holding the 'Option' key while clicking the 'Go' menu in Finder.

Frequently Asked Questions

What file format does Adobe Acrobat use for custom stamps?

Adobe Acrobat stores custom stamps as standard PDF files. Each page within the PDF file functions as an individual stamp in the application's stamp palette.

Will this migration method work for Acrobat Reader DC?

Yes, the process is nearly identical for the free Acrobat Reader. However, you will need to look for the 'Acrobat Reader' folder instead of 'Acrobat' within your Library/Application Support directory.

Why didn't my custom stamps migrate automatically?

When upgrading across major versions (such as from 9.5 to DC), the software architectures and folder directories change significantly. The installer often creates a fresh user profile folder rather than risking corruption by pulling from legacy directories.
