How to Create a Dynamic PDF Stamp with Fillable Text Fields
Question details
The user needs to create an interactive dynamic stamp in a PDF that contains predefined text fields, allowing users to input specific data (such as approval amounts or VAT) when placing the stamp.

- Product
- Adobe Acrobat
- Device & OS
- not provided
- Scenario
- Setting up a document approval workflow where variable information must be collected from the user at the exact moment a custom stamp is applied.
- Observed behavior
- The user requires a solution to integrate fillable form fields into a stamp, but may be encountering limitations due to the differences between standard and professional PDF editor versions.
Verify that your PDF editor supports advanced scripting, document-level JavaScript, and page templates, as these features are necessary for creating fully interactive dynamic stamps.
Use Acrobat Pro and JavaScript for Dynamic Stamp Creation
Utilize advanced form fields and document-level JavaScript available in professional PDF editors to prompt users for input when stamping.
Creating custom dynamic stamps that request user input is an advanced process. It requires the Page Template function and document-level JavaScript to trigger input dialogs. These specific capabilities are fully supported in Adobe Acrobat Pro, while Acrobat Standard users often face functional limitations.
Create the visual layout of your stamp using a PDF authoring tool or graphic design software, leaving blank spaces where the variable data will go, and save the file as a PDF.
Open the base stamp PDF in Acrobat Pro, navigate to the 'Prepare Form' tool, and insert text fields into the blank spaces where user input (such as an approval amount) is required.
Write and apply a custom JavaScript script to the text fields. This script should be designed to generate a pop-up prompt asking the user to enter the required data whenever the stamp is applied.
Navigate to the 'Stamp' tool palette, select 'Custom Stamps,' and import your newly created interactive PDF file into your stamps category to use it on future documents.

Manage PDF Forms and Custom Stamps with WPS Office
WPS Office offers a robust suite of PDF tools that simplify inserting custom stamps, managing fillable forms, and streamlining document approval workflows without the complexity of heavy scripting.
- 1. Open your document: Launch WPS Office and open the PDF document that requires stamping or form filling.
- 2. Access the Stamp tool: Navigate to the 'Comment' tab on the top ribbon and click on the 'Stamp' icon to view the available pre-made stamps.
- 3. Add a Custom Stamp: Click 'Click to Add' or 'Custom Stamp' from the dropdown menu to upload your own stamp image or business seal.
- 4. Fill PDF Forms: To input variable data natively, navigate to the 'Form' tab and interact directly with fillable text fields present in the document.

Frequently Asked Questions
Can I create dynamic stamps in Adobe Acrobat Standard?
Creating complex dynamic stamps that prompt users for input typically requires the Page Template function and document-level JavaScript. Because these features are generally restricted to Adobe Acrobat Pro, Standard users usually cannot create fully dynamic interactive stamps.
What is a dynamic PDF stamp?
A dynamic PDF stamp is an interactive annotation that automatically retrieves or requests information—such as the user's name, the current date and time, or custom text input like an approval amount—at the exact moment the stamp is applied to a page.
Do I need to know JavaScript to make a dynamic stamp?
Yes, to create custom dynamic stamps that prompt users for fillable text fields or calculate data on the fly, you will need a basic understanding of document-level JavaScript to script the interactive prompts and data population.
Why are my text fields not updating when I place the stamp?
If your text fields aren't updating, the JavaScript might not be correctly tied to the stamp's calculation event, or the specific PDF reader you are using to place the stamp may not support executing dynamic scripts.
