WooCommerce PDF Watermark allows you to stamp/watermark eBooks and other PDF downloadable files with custom text or images to prevent and identify unauthorized sharing. You can also protect PDF files further by enabling copy, print and modification protection, as well as password-protecting your files.

Requirements

• Hosting server must have FPDF installed
• PDF Version should be 1.4 and under
• PDF should contain no layers

Certain hosting environments use security settings that prevent PDF Watermark from working properly. If you encounter difficulty, manually upload your PDF file via FTP to your site’s root folder.

1. Download the .zip file from your WooCommerce account.
2. Go to: WordPress Admin > Plugins > Add New and Upload Plugin with the file you downloaded with Choose File.
3. Install Now and Activate the extension.
