FLAC is the standard for archiving and for hi-fi players that refuse AAC. The conversion cannot restore detail AAC already discarded, but it freezes the current quality in a lossless, open format that will still be readable in ten years.
Drop your AAC file above and Morphix decodes it locally, then re-encodes it as FLAC using WebAssembly + the browser's native codecs. Nothing is ever uploaded — your files stay on your device. Batch as many files as your machine can handle.
