The WooCommerce PDF Watermark extension is a plugin designed to protect and secure PDF downloads on your WooCommerce-powered online store.

It provides various features to help safeguard your PDF documents, including adding text or image watermarks, password protection, copy protection, print protection, and modification protection.

With the plugin, you can easily add custom text or image watermarks to your PDF files to prevent and identify unauthorized sharing.

You can choose to add watermarks on a global, product, or variation level, giving you the most control over what watermarks you want to place on what products.

The text watermarks can be personalized based on the customer who purchased the product through a template tag system.

The WooCommerce PDF Watermark plugin also allows you to protect your PDF files further by enabling copy, print, and modification protection, as well as password-protecting your files.

When the copy protection is enabled, the plugin flattens the images and text, making them difficult for people to extract from your document.

The print protection blocks the unauthorized printing of your store’s PDF documents. The modification protection feature prevents others from editing your PDF documents and removing watermarks.

In addition, the plugin lets you choose which pages the watermark should be shown on. You may only want to show a watermark on the first or last pages of your PDF documents, and this plugin lets you change where these watermarks appear.

Overall, the WooCommerce PDF Watermark extension is an essential tool for WooCommerce store owners who want to add an extra layer of security and branding to their PDF documents.

It is user-friendly, highly customizable, and offers a variety of protection features to keep your PDF downloads safe and secure.
