PDF Stamping basics

When you upload a PDF file and click Add, you will see the following checkbox in the Edit tab of your product.

Click that box, then Save changes, and the first page of your PDF will be stamped with the customer's email and the Gumroad coat of arms.

When you apply a PDF stamp to your ebook, your customer will not have automatic access to it, because Gumroad has to process the PDF file and apply the individualized stamp. This can take from several seconds to several minutes, depending on the size of the PDF file. When the PDF stamp is ready, your customer will receive a download link in their email receipt. We suggest that you mention this delay in your product description to avoid confusion.

Your customer will also not be able to read your ebook through their Gumroad library if it is PDF stamped. Instead, they can download the ebook and read it through any device they choose.

FAQs:

Q: Can I add password protection AND a PDF stamp to my PDF?
A: Nope! For more information, see this guide.

Q: What does PDF stamping do? Is it a kind of DRM?
A: It serves as a disincentive for customers who might abuse their ownership of your PDF. This is not the same thing as DRM protection. Gumroad does not have DRM solutions for authors wishing to license their products to customers.

Q: Does every page of the PDF get stamped?
A: No, just the first page.
