Stamp every PDF with the buyer's details
DPD adds each buyer's name and email to every page, and can lock the PDF against printing and copying.

Ebooks get shared. When every page of a buyer’s copy carries their name and email, most people think twice before posting it online. And if a copy does turn up somewhere, you’ll know whose it was.
How stamping works
Upload your PDF to DPD and turn on stamping. When someone buys, DPD makes their own copy with their name and email on every page, before they download it. You choose where the stamp sits on the page and its color, so it can stay out of your design’s way. There’s no code, and nothing to do per order.
Encryption, if you want it
DPD can also encrypt each buyer’s copy and block printing, copying text, or both. Some mobile reading apps can’t open encrypted PDFs, so it’s optional. Leave printing allowed for workbooks, planners and other PDFs people are meant to print.
Good for
- Ebooks and guides you’d rather not see on a file-sharing site

Questions
What does the stamp show?
The buyer’s name and email, on every page of their copy. You choose where it goes on the page and its color.
Can I stamp a PDF that's already encrypted?
No. Upload it unencrypted so DPD can add the stamp, then turn on encryption in DPD to lock each buyer’s copy afterwards.
Does encryption work on every device?
Most PDF readers open encrypted PDFs, but some mobile apps can’t. That’s why encryption is optional, and stamping works on its own.
