What happens when converting 3GP to MP3?
The 3GP data is decoded inside your browser with WebAssembly and re-encoded to the MP3 specification, so no file is ever uploaded to a server. MP3 uses lossy compression: the file gets far lighter, but a small amount of fine detail is discarded in the process. 3GP supports animation while MP3 does not, so only the first frame is kept. Audio is re-encoded with the MP3 codec while keeping the original duration, so audio and video stay in sync.
