How to Flatten a Dynamic PDF Stamp Automatically
Question details
The user wants to know if a dynamic PDF stamp script can automatically flatten the page or annotation it is applied to during execution.
- Product
- Device & OS
- not provided
- Scenario
- Applying dynamic stamps via scripts to PDF documents and attempting to flatten them automatically to prevent further edits.
- Observed behavior
- The script fails to flatten the stamp because the stamp script runs before the annotation is actually applied to the destination document. The script context refers to the stamp document rather than the destination PDF.
Always create a backup copy of your PDF document before flattening, as the flattening process permanently removes editable annotation properties and cannot be undone.
Apply the Stamp First and Flatten Using an Automation Script
Since a stamp cannot flatten itself while running, you must apply the stamp first and then trigger a separate script to flatten the document.
When a dynamic stamp script executes, the stamp has not yet been applied to the target document. The JavaScript context refers to the stamp file itself, making self-flattening impossible.
To resolve this, separate the stamping and flattening actions by using an external document-level script or action wizard.
Insert your dynamic stamp onto the desired PDF page either manually or via your initial deployment script.
Create a separate document-level JavaScript or an automation action that executes after the stamp is fully placed.
Use the JavaScript command 'this.flattenPages();' in your new automation script to flatten the annotations on the target document.
Save the target document to permanently lock the applied stamp and flatten the layers into the base PDF.

Frequently Asked Questions
Why does my dynamic stamp script give an error when trying to flatten?
The script runs before the stamp is physically applied to the destination PDF page. At the moment of execution, the stamp doesn't exist on the page, and the script's reference targets the original stamp file instead of the document.
Can I undo a flattened PDF stamp?
No, flattening a PDF permanently merges the annotations and stamps into the base layer of the document. Always keep a backup of the original unflattened PDF in case you need to make future edits.
Does WPS PDF support viewing and flattening stamps?
Yes, WPS PDF supports viewing, adding, and flattening standard stamps effortlessly. While executing complex Adobe-specific JavaScript dynamic stamps may require specific environments, WPS excels at standardizing and flattening final documents securely.
