How to Find Custom Dynamic Stamps in Acrobat X for Mac
Question details
The user needs to locate a custom dynamic stamp file created in Adobe Acrobat X on Mac to edit its JavaScript.

- Product
- Adobe Acrobat X
- Device & OS
- Mac
- Scenario
- Editing the JavaScript of a custom dynamic stamp within a PDF editor.
- Observed behavior
- The custom stamp file cannot be found in the standard Library, Application Support, or Plug-ins folders usually checked by the user.
Ensure you have administrator privileges on your Mac, as accessing hidden Library folders requires appropriate system permissions.
Locate Custom Stamps in the Hidden User Library
Access the hidden User Library folder to find the correct Acrobat Stamps directory where custom dynamic stamps are stored.
Custom stamps are typically stored in the user's Acrobat Application Data folder rather than the main Plug-ins folder. Because the user Library is hidden by default on Mac, you must use the Go to Folder feature to access it.
Open Finder on your Mac. Click on the 'Go' menu at the top of the screen and select 'Go to Folder', or press Shift + Cmd + G.
Type the path `~/Library/Application Support/Adobe/Acrobat/` into the search bar and press Enter to access the hidden user library directory.
Open the folder corresponding to your Acrobat version (for Acrobat X, this is typically '10.0'), then open the 'Stamps' folder inside it.
Look for the PDF file containing your custom dynamic stamp. Because Acrobat renames custom stamps with a random alphanumeric string, sort the files by 'Date Modified' to easily identify your recently created stamp.

Easily Add and Manage Custom PDF Stamps in WPS Office
Avoid navigating complex hidden system folders. WPS PDF allows you to easily create, manage, and insert custom stamps directly from an intuitive user interface.
- 1. Open Your PDF in WPS Office: Launch WPS Office and open the PDF document you want to stamp.
- 2. Access the Stamp Tool: Navigate to the 'Comment' tab on the top ribbon and click on the 'Stamp' icon.
- 3. Add a Custom Stamp: Select 'Custom Stamp' from the dropdown menu to upload your own image, signature, or custom design.
- 4. Place the Stamp: Click anywhere on the PDF page to place, move, or resize your newly created custom stamp.

Frequently Asked Questions
Why does Acrobat rename my custom dynamic stamps?
Adobe Acrobat automatically assigns a unique alphanumeric file name to custom stamps when they are generated. This prevents naming conflicts within the application's internal database when managing multiple stamps.
Can I edit the JavaScript of a stamp after creating it?
Yes. Once you locate the exact PDF stamp file in the Application Support folder, you can open it directly in Acrobat, access the Page Templates or form fields, and modify the JavaScript code.
How do I permanently unhide the Library folder on Mac?
Open Finder, navigate to your Home folder, press Cmd + J to open View Options, and check the box that says 'Show Library Folder'. This makes the Library folder permanently visible in your Home directory.
