PDF file stamping
In this article:
PDF stamping has proven to be a successful method against piracy. It discourages buyers from sharing your product elsewhere online because their credentials will be available for everyone to see. It literally stamps the buyer's email address at the bottom of every single page of the document.
Important! Do not apply pdf stamping to password-protected pdf files. Your customers will not be able to download the file. You can use either the password or the stamp, but not both.
How the PDF stamp looks
Note: If you're using full-page visuals or other specifically formatted content at the bottom of the pdf document pages and you want to make sure that the stamp won't interfere with that, you may want to test it by downloading your own stamped product from your store.
How to apply the PDF stamp
1. Upload a product file in pdf. format
2. Check the Enable PDF stamping box
When you can't use the PDF stamp
If you're uploading a compressed file like a .zip or .rar file, you won't be able to use the PDF stamp. The file will already be compressed before you upload. If you'd like to use the PDF stamp, you'll need to upload the file as a PDF.
If you would rather use a password protected PDF document, then you will need to use either the password or the PDF stamp. They will not work properly together.
