The GoPro raw files is basically Adobe DNG with CineForm compression.
You can download the Adobe DNG converter and transform the GPR files into DNG.

If you convert from GPR to DNG format the files will no longer be compressed and thus much bigger (13 - 15 MB).
If your chosen picture editor can open GPR files there is really no beed to convert to DNG first, but a lot of programs does not suppoprt GPR files directly and thus an extra conversion step to DNG is necessary.
