What happens when converting FLAC to M4A?
The FLAC data is decoded inside your browser with WebAssembly and re-encoded to the M4A specification, so no file is ever uploaded to a server. M4A can encode losslessly, so this conversion adds no further quality degradation to data that is already compressed.
