How to Automatically Add a Logo Stamp to a PDF Using PDF.co and Zapier

Step 1: Set Up the Trigger

Create a Zap and select the app that supplies the PDF. For example:

• App: Google Drive
• Trigger event: New File in Folder

Connect your account, select the folder containing incoming PDFs, and test the trigger with a sample file.

Step 2: Add the PDF.co Action

Add another step:

• App: PDF.co
• Action: Add Image to PDF

Connect your PDF.co account by signing in and authorizing Zapier.

Step 3: Configure the Logo

Configure the PDF.co action:

• Source PDF URL: Map the PDF file from the trigger.
• Image URL: Enter the direct URL of the logo or map it from a previous step.
• X: Enter the horizontal position of the image.
• Y: Enter the vertical position of the image.
• Pages: Enter 0 for the first page or 0- for every page.
• Width: Enter the desired image width.
• Height: Enter the desired image height, or leave it empty if the action can preserve the image’s proportions.
• Keep Aspect Ratio: Select True.
• Output PDF Name: Enter a filename such as stamped-document.pdf.

PDF.co page indexes begin at 0. The X and Y coordinates are measured from the upper-left corner of the page.

Use the PDF Inspector to determine suitable coordinates and dimensions for the logo.

Step 4: Test the Action

Test the PDF.co step. When processing finishes, PDF.co returns a URL for the stamped PDF.

Open the URL and confirm that the logo appears on the intended pages at the correct position and size.

Step 5: Save the Result

PDF.co output URLs are temporary. Add another Zapier action to save the generated PDF to Google Drive, Dropbox, OneDrive, or another permanent destination.

Map the PDF.co output URL into the destination app’s file field.
