Convert 3PG to MP3

Converting 3PG files directly to MP3 Audio Files (.3pg to .mp3 conversion) is not possible, since 3PG is a non-existing format.

Perhaps this is just a typo, and you are actually searching for ways how to convert 3GPP Multimedia Files to MP3 Audio Files. In that case, please refer to the 3GP to MP3 conversion entry.

In a word, direct 3pg to mp3 conversion is not possible.
So don't expect any so-called 3pg to mp3 converter or 3pg to mp3 free online conversion tool available.
