About M4A (AAC) to FLAC conversion
This tool converts M4A (AAC) files to FLAC entirely on your device. The conversion runs locally in your browser using WebAssembly, so your audio files are never uploaded to a server.
M4A is AAC audio in an MP4 container, the standard format for iTunes and Apple devices.
FLAC is a lossless audio format that compresses audio without throwing away any quality.
