Hi Guido,
Thank you for your interest in Syncfusion products.
You may create a PdfTemplate of the loaded page and draw at a new position in a new PdfDocument. Please refer to the code snippet given below:
PdfPage page = doc1.Pages.Add();
PdfGraphics g = page.Graphics;
PdfPageBase lpage = doc2.Pages[0];
PdfTemplate template = lpage.CreateTemplate();
g.DrawPdfTemplate(template, new PointF(100,100), page.GetClientSize());
Also, following is the link to our documentation which explains the same:
