I am sorry if i am posting this question in wrong page.
Is there a way to find out source file format or extension(the file from which it was converted) like microsoft word, excel or image file etc from which it was converted to pdf file at the first place.
for example if somebody converts a ms word file to pdf and send it to me. How can i know that the pdf file was converted from ms word.
Is there any way to find it?
Thanks in advance
