AAC to FLAC Converter

Convert AAC audio to FLAC without uploading the file.

To convert AAC to FLAC, drop the file in and pick a bitrate. FLAC is lossless compression — bit-identical to the original at roughly half the size of WAV. The right archive format for anything you cannot re-rip. The conversion runs through FFmpeg in WebAssembly inside your browser, so recordings, interviews and unreleased music never touch a server.

About converting AAC to FLAC

FLAC is lossless compression — bit-identical to the original at roughly half the size of WAV. The right archive format for anything you cannot re-rip. Converting from AAC, which is already lossy, cannot restore what its encoder discarded — a second lossy encode only ever removes more.
