Editable pdf file textbox, checkbox, etc. doesn't write after creating pdf file from itextsharp this file should not be editable code below: pdfStamper.FormFlattening =  true ;

If you have base64 code image or image path, easily can add image in PDF from iTextSharp. Code below: PdfReader pdfReader =  new  PdfReader( "C:\\file.pdf" ); PdfStamper pdfStamper =  new  PdfStamper(pdfReader,  new  FileStream( "target save path" , FileMode.Create)); string  imagepath =  "base64 image code" ; Byte[] bytes = Convert.FromBase64String(Regex.Replace(imagepath, @ "^data:image\/[a-zA-Z]+;base64," ,  string .Empty)); var  pdfContentByte = pdfStamper.GetOverContent(1);  // page number iTextSharp.text.Image image1 = iTextSharp.text.Image.GetInstance(bytes); image1.SetAbsolutePosition(140, 70); image1.ScalePercent(20f); pdfContentByte.AddImage(image1); pdfStamper.Close();
