What happens when converting MP4 to OGG?
The MP4 data is decoded inside your browser with WebAssembly and re-encoded to the OGG 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. MP4 supports animation while OGG does not, so only the first frame is kept. Audio is re-encoded with the OGG codec while keeping the original duration, so audio and video stay in sync.
