Download Manager PDF Stamper

Description

The PDF Stamper add-on applies custom watermarks to PDF files distributed by the Download Manager, injecting buyer data (name, email, IP, date) directly into the document at the time of download. This embedded trail turns each copy into a unique version, discouraging unauthorized sharing of ebooks, workbooks, reports, and paid materials sold through your WordPress site.

Key Features

• Dynamic watermark: inserts user information into each delivered PDF, generating an individualized file per download.
• Customizable fields: choose which data to stamp on the document, such as name, email, IP address, and transaction date.
• Configurable positioning: set coordinates, opacity, font, and text size applied on the PDF pages.
• On-demand processing: the stamp is applied at the time of the request, keeping the original file intact on the server.
• Native integration with the Download Manager: enables the feature by package, without changing the sales or delivery flow already configured.

Benefits of PDF Stamper

• Leakage deterrence: buyers think twice before redistributing a file identified with their own data.
• Copy traceability: helps identify the source of a PDF if it appears in forums or piracy networks.
• Protection for intellectual content: adds a security layer to infoproducts, without relying on complex DRM.
• Automated operation: the stamping process runs in the background, with no manual intervention for each sale.

Who Is It For?

• Infoproduct creators who sell ebooks, workbooks, and digital PDF materials.
• Publishers, independent authors, and course platforms that distribute proprietary content.
• Companies and consultancies that deliver reports, whitepapers, and confidential documents to clients.

PDF Stamper fits stores that already handle file sales through the Download Manager and need an extra layer against uncontrolled sharing. By personalizing each copy with buyer data, the component drastically reduces the appeal of passing the material along and preserves the commercial value of your digital catalog over time.
