Hi, Heekmaaa.
As for me, I have seldom tried to change upload img to pdf. I wonder have you ever worked it out? Do I need another 3rd party manual toolkit? When it comes toPDF conversion process, I have another question, I wonder have you ever tried toconvert pdf to other image filesbefore? As for myself, I am testing the related PDF to PNG converting , PDF to BMP converting , and PDF to JPG converting programs these days. Do you have experience about it? Any suggestion will be appreciated. Thanks in advance.
