Convert 3PG to 3G2

3gp to 3g2 conversion pretty much describes export between two different variants of 3GP formats, maybe even between same file types with different file extensions. You can easily convert both of these files in different multimedia converters, but perhaps just renaming the file extension should be enough.

Simply put, it is impossible to convert 3PG to 3G2 directly.
Thus, there is no so-called 3pg to 3g2 converter or a free online 3pg to 3g2 converter to be found.
