What happens when converting OGA to AAC?
The OGA data is decoded inside your browser with WebAssembly and re-encoded to the AAC specification, so no file is ever uploaded to a server. AAC uses lossy compression: the file gets far lighter, but a small amount of fine detail is discarded in the process.
