How to Find the Custom Stamps Folder in Acrobat Pro for Mac
Question details
The user needs to locate the custom Stamps folder in Acrobat Pro 2017 on a Mac to migrate their custom stamps from an older Acrobat installation.

- Product
- Adobe Acrobat Pro 2017
- Device & OS
- macOS High Sierra
- Scenario
- Migrating custom PDF stamps to a new Acrobat installation on an updated macOS system.
- Observed behavior
- The user library and the specific custom Stamps directory for Acrobat are hidden by default in the macOS High Sierra Finder.
Ensure you have your old custom stamp files saved in PDF format and ready to be copied over to the new directory.
Reveal the Hidden Library Folder Using the Option Key
Use a built-in keyboard shortcut in Finder to access the hidden user Library folder where Acrobat stores your custom stamps.
By default, macOS High Sierra hides the user's Library folder to protect essential system and application files. To migrate custom stamps, you must temporarily bypass this restriction using the 'Go' menu in Finder.
Click the Finder icon in your Mac's Dock to make it the active application.
Click on the 'Go' menu located in the top menu bar of your Mac screen.
Press and hold the 'Option' (Alt) key on your keyboard. While holding the key, the hidden 'Library' folder will appear in the dropdown list.
Click on 'Library', then navigate through the path: Application Support > Adobe > Acrobat > 2017 > Stamps.
Drag and drop or paste your old custom stamp PDF files into this Stamps folder.

Easily Manage PDF Stamps with WPS Office
WPS Office offers a comprehensive PDF editor that makes it incredibly simple to add, manage, and customize stamps on your PDF documents without the hassle of navigating hidden system folders.
- 1. Open your PDF in WPS: Launch WPS Office and open your PDF document.
- 2. Access the Comment Tab: Go to the 'Comment' tab located on the top navigation ribbon.
- 3. Select the Stamp Tool: Click the 'Stamp' icon to choose from preset stamps, or click 'Custom Stamp' to easily upload your own image or PDF.
- 4. Place the Stamp: Click anywhere on the document to apply and resize your custom stamp as needed.

Frequently Asked Questions
Why can't I see the Library folder in my Mac Finder?
Apple hides the user Library folder by default in modern macOS versions (like High Sierra and later) to prevent users from accidentally deleting or modifying important system and application support files. Holding the Option key reveals it safely.
What file format should my custom stamps be saved as?
Custom stamps in Adobe Acrobat and most standard PDF editors are stored as standard PDF files. Each page within the PDF represents a single custom stamp.
Where are the default Acrobat stamps stored on a Mac?
While user-created custom stamps are stored in the user-level Library folder, the default factory stamps that come with Acrobat are typically stored in the system-level Application Support folder, usually located at /Library/Application Support/Adobe/Acrobat/[Version]/Stamps.
