What happens when converting AAC to AIFF?
The AAC 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.
