What happens when converting MOV to M4A?
The MOV data is decoded inside your browser with WebAssembly and re-encoded to the M4A 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. MOV supports animation while M4A does not, so only the first frame is kept. Audio is re-encoded with the M4A codec while keeping the original duration, so audio and video stay in sync.
