- Product
- Adobe Acrobat Pro DC
- Device & OS
- not provided
- Scenario
- Adding personalized stamps to PDF documents that auto-update with current information, such as dates or user names.
- Observed behavior
- The user is looking for the correct workflow and configuration steps to build or alter stamps with dynamic data fields using Acrobat Pro DC.
Ensure you have a base PDF or image file ready to use as your stamp graphic, and identify the specific dynamic values (like the current date or your name) you want to include.
Create a Custom Stamp and Configure Dynamic Fields
Use Acrobat's custom stamp tool to import your base graphic, then use the Prepare Form tool to add JavaScript-powered dynamic values.
The exact workflow for creating dynamic stamps can vary slightly depending on your version of Acrobat and operating system. Generally, you create a static stamp first, locate where Acrobat saved it, and then edit that specific stamp file by adding form fields powered by JavaScript.
Open Acrobat Pro DC, navigate to 'Tools' > 'Stamp' > 'Custom Stamps' > 'Create'. Browse for your base PDF or image file, select it, and click 'OK'. Assign it to a category and give it a name.
Find the Acrobat Stamps folder on your computer. On Windows, this is typically located at 'C:\Users\[Username]\AppData\Roaming\Adobe\Acrobat\[Version]\Stamps'. Open the newly generated PDF file found in this folder.
With the stamp file open, go to 'Tools' > 'Prepare Form'. Add a 'Text Field' over the area where you want your dynamic information to appear. Name the field appropriately.
Right-click the text field and select 'Properties'. Go to the 'Calculate' tab, choose 'Custom calculation script', and click 'Edit'. Enter the required JavaScript code to pull in the dynamic data (e.g., code for the current date or time), then click 'OK' and save the PDF file.

Easily Create and Apply Custom Stamps with WPS PDF
WPS Office includes a highly capable PDF editor that allows you to quickly add pre-designed stamps or create your own custom text and image stamps without dealing with complex JavaScript configurations.

- 4. Customize and save: If creating a text stamp, type your desired content (such as your name or a specific date), adjust the color and shape, and click 'OK'.
- 5. Apply the stamp: Click anywhere on your PDF document page to place your newly created custom stamp.

Frequently Asked Questions
Where are custom stamps saved in Adobe Acrobat Pro DC?
In Windows, custom stamps are typically saved in the user directory under 'AppData\Roaming\Adobe\Acrobat\[Version]\Stamps'. On a Mac, they are located in 'Library/Application Support/Adobe/Acrobat/[Version]/Stamps'.
Can I use images like PNG or JPG for custom stamps?
Yes, Acrobat allows you to import various image formats such as JPEG, PNG, or BMP. During the custom stamp creation process, Acrobat automatically converts the imported image into a PDF format to serve as the stamp.
Why is my dynamic stamp not updating the date?
If the date is not updating, the JavaScript calculation within the stamp's text field may be incorrect, or the field properties might not be set to calculate. Ensure the script is properly formatted and set to execute dynamically.
Do I need programming skills to create dynamic stamps?
Creating dynamic stamps requires adding basic JavaScript to the form fields within the stamp file. While extensive programming knowledge isn't necessary, you must follow specific JavaScript syntax snippets, which can often be found in Adobe's community forums and documentation.
