- Product
- Microsoft Word
- Device & OS

- Scenario
- Creating individual, encrypted PDF files from a data source using the mail merge functionality.

Use the Community Merge Tools Add-in with Bullzip PDF Printer
Since Microsoft lacks a native tool for this exact scenario, use a trusted community add-in to generate and encrypt individual PDFs during your mail merge.
The Merge Tools Add-in is a customized, community-supported tool that extends standard mail merge capabilities. When paired with the Bullzip PDF Printer, it allows you to create and individually encrypt PDF files for each record in your data source.
Navigate to the official Microsoft Answers forum and search for the 'Downloading Merge Tools Add-in' thread to download the latest version of the customized add-in.
Download and install the Bullzip PDF Printer from its official website. This virtual printer is required by the add-in to generate the PDF files before encryption.
Extract the downloaded Add-in files and copy them into your Microsoft Word Startup folder so that the tool loads automatically when you launch the application.
Open Word, navigate to the newly added Merge Tools tab on your ribbon, select your document and data source, and follow the prompts to configure unique password protection for each output PDF.
