As for me, I have seldom tried to upload image and convert to a Tiff and a PDF. I wonder have you ever worked it out? Do I need another 3rd party manual toolkit? When it comes to PDF converting process, I have another question, I wonder have you ever tried to convert pdf to other image files before? As for myself, I am testing the related PDF to JPG converting, PDF to Multi-Tiff converting , and PDF to Tiff converting programs these days. Do you have experience about it? Any suggestion will be appreciated. Thanks in advance.
