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