There are several journal websites (typically Taylor and Francis) that require that all PDF files submitted to it for reviewing should be Adobe PDFs. The submission engine will not accept a PDF generated by LaTeX or OpenOffice.
To do this conversion, one has to actually boot into Windows, open the PDF file with Adobe Acrobat Reader, save as a new file and then upload the paper to the journal website. This is is kind of a funny procedure and hampers the freedom.
What software can I install, so that I can denote the PDF as an Adobe PDF, so that I can easily submit the paper to the journal website.
