3GP was the standard video format for early mobile phones (Nokia, early Android). These small files are hard to play on modern devices.

Will the small 3GP file become larger as MP4?

MP4 files may be slightly larger, but will be compatible with all modern devices and software.

Can I convert 3G2 files too?

Yes, both 3GP and 3G2 mobile video formats are supported.
