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