Hi Kevin,
Thank you for your interest in Syncfusion Products.
You can add more pages to an existing PDF by using IPDFPageCollection.Add method.
[C#]
IPDFPage page;
for (int i = 0; i <= 5; i++)
{
// Create new page
page = pdfDoc.CreatePage();
//Add to existing document
pdfDoc.Pages.Add(page);
}
Please refer the sample in the below link which illustrates the above:
