Conversion of pdf files to gp5 file format

Although Guitar Pro can export music sheets as PDF documents, it does unfortunately not work the other way, hence pdf to gp5 conversion is likely not possible. It is unlikely you can achieve this this conversion directly, however some programs claim to allow conversion of music sheets in PDF formats to MusicXML format which you could import to Guitar Pro. Your best option in this case would be to look for some OMR solution.
