Solution 1Recommended

Apply Stamps Using a Desktop PDF Application

Since the online application lacks stamp support, you must use a desktop PDF reader or editor to insert corporate stamps.

Online PDF editors often restrict complex scripts like JavaScript due to browser security limitations. To use dynamic or custom corporate stamps, transitioning to a desktop environment is required.

1
Download the PDF file

Save the PDF document from your online workspace or email directly to your local computer drive.

2
Open in a desktop application

Launch the Adobe Acrobat desktop app (or a compatible desktop PDF editor) and open the downloaded document.

3
Insert the stamp

Navigate to the 'Tools' or 'Comment' section, select the 'Stamp' feature, and apply your custom corporate JavaScript stamp to the page.

Frequently Asked Questions

Can I use JavaScript-based dynamic stamps in web browsers?

Most online PDF editors, including Adobe Acrobat online, do not support JavaScript dynamic stamps due to strict web browser security policies. You must use a desktop application for these advanced features.

Will stamps applied in a desktop app show up in online viewers?

Yes, WPS Office supports applying predefined stamps as well as allowing you to import your own custom image stamps for document approval and review.
