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