What happens when converting 3GP to OGA?
The 3GP data is decoded inside your browser with WebAssembly and re-encoded to the OGA specification, so no file is ever uploaded to a server. Both formats rely on comparable compression, so file size and perceived quality stay in the same range. 3GP supports animation while OGA does not, so only the first frame is kept. Audio is re-encoded with the OGA codec while keeping the original duration, so audio and video stay in sync.
