Answer 1

jsPDF can't do this, but pdf-lib can. You can combine the two, or just use pdf-lib on its own. To load an existing pdf in pdf-lib, just do this:

async function loadPdf(){
  const response = await fetch('existing.pdf');
  const buffer = await response.arrayBuffer();
  const existingPdfDocBytes = new Uint8Array(buffer);
  const pdfDoc = PDFLib.PDFDocumentFactory.load(existingPdfDocBytes);
  return pdfDoc;
}
