PDF Stamp / Watermark

To add an extra layer of protection to your PDF files, you can automatically stamp (or watermark) them. A stamp makes it more difficult for buyers to share your files.

What is a PDF stamp?

A PDF stamp is a security measure that prevents illegal sharing of the PDFs that you sell. Through this process (called "stamping"), each page of your PDF file(s) is stamped with the buyer's name and e-mail address.
How stamps work at Tentary

Just follow these steps:
  1. Create a new product in your Tentary account
  2. Upload a .pdf file

A stamp can only be applied to
  • PDF files
  • Files smaller 1000MB
  • files that are not password protected
  • files that are not read-only
If multiple files are sold with one product (e.g. a few PDFs and a video), the stamp will only be applied to the PDFs.
