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