How to Add a Watermark to PDF Files
If you have a business, you really want to add a watermark to your PDF files to avoid stealing. The worst part would be to add a watermark to thousands of PDF files. The good news is that you can actually automate the process using PDF.co Web API and Zapier.
Here’s a step-by-step guide. We will use this sample PDF invoice for this tutorial and add a watermark to it.

Step 1: Create a Zap
- On your Zapier dashboard, click Create Zap
Step 2: Select a Trigger App
