What happens when converting 3GP to MP4?
The 3GP data is decoded inside your browser with WebAssembly and re-encoded to the MP4 specification, so no file is ever uploaded to a server. MP4 uses lossy compression: the file gets far lighter, but a small amount of fine detail is discarded in the process.
