Go to the PDF Rebrander tab in the plugin.
Configure your CTA Page Settings at the top: headline, description, button text, button color, and optional image.
Choose the CTA Placement: First Page Only, Last Page Only, or Both (first and last).
Scroll down to the funnel list. Select the funnels you want to rebrand using the checkboxes (or use "Select All").
Click the Rebrand Selected PDFs button.
Wait for the process to complete. Each PDF takes a few seconds. A progress indicator shows you the status.
Important: Rebranding PDFs is server-intensive. If your server has a low PHP memory limit (below 128M), you may get a 500 error. Ask your host to increase memory_limit to at least 256M.
