How to Share Custom Acrobat Stamps with Another User
Question details
The user wants to export and share custom PDF stamps created in Adobe Acrobat so that another person can use the exact same stamps on their computer.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- A user has created custom stamps in their PDF editor and needs to distribute this stamp library to colleagues or clients for standardized document review.
- Observed behavior
- Custom stamp libraries are not automatically embedded in the standard PDF file. To reuse the stamps natively from the application's toolbar, the recipient must manually install the custom stamp file into their local application directory.
Ensure both you and the recipient have Adobe Acrobat installed and are familiar with locating hidden system folders on your respective operating systems.
Locate and Share the Custom Stamp Library File
This is the best method if you want the recipient to have permanent access to your custom stamps in their Acrobat stamp menu.
Acrobat stores custom stamps as background PDF files in a specific system directory. By finding this file and sharing it, the recipient can install the entire library into their own Acrobat setup.
Open your file explorer. On Windows, navigate to 'C:\Users\[YourUsername]\AppData\Roaming\Adobe\Acrobat\[Version]\Stamps'. On a Mac, go to '/Users/[YourUsername]/Library/Application Support/Adobe/Acrobat/[Version]/Stamps'.
Look for a PDF file in this folder. Acrobat usually generates random names for custom stamp library files. You can open the PDF briefly to verify it contains your custom stamps.
Copy this specific PDF file and send it to your recipient via email, shared network drive, or cloud storage.
Have the recipient download the file and place it into the exact same 'Stamps' directory path on their computer. They must then restart Acrobat for the stamps to appear in their menu.

Share Stamps Within a PDF Document
A quick workaround for users who only need to use the stamp occasionally and do not want to navigate system folders.
Use WPS Office for Easy PDF Editing and Stamping
If you find managing and transferring Adobe Acrobat stamp files through hidden system directories complicated, consider trying WPS Office. It provides an intuitive, lightweight PDF editor that makes adding, organizing, and collaborating on PDF annotations effortless.

Frequently Asked Questions
Where are custom Acrobat stamps stored on Windows?
On Windows, custom stamps are saved as PDF files in a hidden system folder, typically located at C:\Users\[Username]\AppData\Roaming\Adobe\Acrobat\[Version]\Stamps.
Where does a Mac store Acrobat stamp libraries?
On macOS, the custom stamp libraries are stored in the user library folder. You can usually find them at /Users/[Username]/Library/Application Support/Adobe/Acrobat/[Version]/Stamps.
Why can't my recipient see the stamps in their Acrobat menu?
Stamps applied to a document can be seen by anyone viewing the PDF. However, if the recipient wants to reuse the stamp from their own application menu, they must physically install the custom stamp library file into their local Acrobat 'Stamps' folder.
Can I rename the custom stamp PDF file before sharing?
Yes, you can rename the randomized PDF file before sharing it to make it easier to identify. Acrobat will still recognize the internal stamps as long as the file remains a valid PDF placed in the correct Stamps directory.
