I submitted a paper to a conference and now they are asking me to change my pdf from PDF/A to normal PDF because editing functions are disable. Looking in the Internet, I found the following post
I use Ubuntu with Document Viewer to open PDF doculents. I installed Acrobat Reader 9 to see if I find something to convert the PDF, but I had not success. Also, my PDFs are generated by pdflatex.
By reading the aforementioned post I understood that I have to have Adobe Acrobat to do the conversion, so have the following question: can I covert the PDF in Ubuntu, it is up to the person reading the document or what should I do?
