A paid eBook, report, course workbook, or template can be forwarded, reposted, or shared with an entire team in seconds. Sending the same unmarked file to every customer makes unauthorized sharing difficult to discourage and almost impossible to trace.
PDF Watermark for WooCommerce automatically creates a protected copy of your document when a customer downloads it. Add identifying customer details, your branding, and optional document restrictions without manually preparing a separate file for every order.
PDF Watermark for WooCommerce helps stores protect valuable downloadable content, including:
The protected file is generated when the customer downloads it. Your original document remains unchanged in your media library.
Generic files are easy to pass around. A personalized watermark connects the downloaded document to the customer or order that received it, helping discourage casual sharing and making distributed copies easier to identify.
Add dynamic information to your text watermark using:
Personalized watermarking also works with guest customer downloads, so buyers do not need to create an account before their files can be protected.
Choose the watermark style that best fits your content and brand. Add personalized text, a logo or branded image, or use both together.
Control how your text watermark looks and where it appears. Available options include:
Add your logo or another branded image to your downloadable files. Adjust its opacity, alignment, and placement so your brand stays visible without distracting from the document.
A single global watermark may not suit every item in your catalog. Start with store-wide settings, then override them for individual downloadable products.
You can also apply separate settings to individual product variations. This is useful when you sell different editions, licenses, packages, or file types from the same product page.
Protect the document without placing a watermark on every page. Choose the option that works best for the design and purpose of each file:
Use the built-in preview tool to check the current watermark, placement, and styling before customers download the document.
A visible watermark can discourage sharing, while access controls and PDF permissions can make common forms of unauthorized use more difficult.
Require customers to enter either their email address or order number before opening the protected PDF. The password is tied to information the customer already received with their order.
Apply PDF permissions that help prevent users from copying or extracting text and images in supported PDF readers.
Disable standard print functionality in supported PDF readers when your licensing terms allow digital access but not printed distribution.
Apply permissions that help prevent customers from editing document content, adding annotations, or changing form fields. These settings can be enabled independently, allowing fillable forms to remain usable when form restrictions are not selected.
PDF permissions depend on the reader used to open the document. They are designed to discourage common misuse, but no digital protection method can guarantee that content will never be reproduced.
Create text watermarks containing international characters with Unicode-compatible fonts such as Arial or DejaVu Sans. You can also upload a custom TTF font when your language or branding requires additional character support.
The extension supports PDFs containing internal navigation links and fillable forms. It also includes optional EPUB watermarking for stores that sell eBooks in both PDF and EPUB formats.
The PDF Watermark Dashboard gives you a clear view of protection activity across your store. Use it to confirm that downloads are being processed successfully and identify files that may need attention.
Dashboard reporting includes:
Configurable activity logging provides additional detail when you need to investigate an incompatible file or share information with support.
Organized settings guide you through the main setup areas: watermark content, appearance, document protection, and logs. Status indicators show whether a basic watermark is configured and whether additional protection settings are enabled.
Start with a simple text or image watermark, preview the result, and add advanced controls only when your products require them.
Some documents open normally on a computer but contain unusual font, encoding, or export settings that make them difficult for other software to process.
If the issue continues, review the recent activity logs or contact WooCommerce support for help investigating the file and extension settings.
