Combining PDFs into a master PDF document is a perfect workflow to automate. In Power Automate, we can accomplish that without writing any code, and we can pull PDF documents from a wide range of connected applications.

In this walkthrough, we’ll learn how to merge two PDF documents in Power Automate using a Cloudmersive Document Conversion connector action.

To begin, we’ll create an instant cloud flow.

Next, we’ll add two Get file content actions to retrieve PDF documents from different locations in our system.

To find our PDF merge action, we’ll add a new action and search for Cloudmersive connectors. This brings up a list of different connector options; we’re looking for the Document Conversion connector with the green logo.

Once we click “See more” to view the actions list, we’ll search for an action called Merge Two PDF Files Together.

After we select this action, we’ll need to create our connection before we can configure our request. We’ll need a free Cloudmersive API key to authorize our requests, and we can get one by visiting the Cloudmersive website & creating a free account (this allows up to 800 API calls per month with zero commitments; our total will reset each month in perpetuity).

Now we’ll configure our request by adding our PDF file contents and file names into each respective parameter.

To create our merged PDF, we’ll add a Create file action and use output content from the Merge PDF action.

Now we’ll save and test our flow.

We’ll find our new PDF in the folder we specified.

That’s all there is to it! We can automate this flow to merge PDF documents directly from SharePoint Lists, Outlook emails, and more.
