About WAV to M4A (AAC) conversion
This tool converts WAV files to M4A (AAC) entirely on your device. The conversion runs locally in your browser using WebAssembly, so your audio files are never uploaded to a server.
WAV is uncompressed audio: perfect quality, large files, and universal support in editing tools.
M4A is AAC audio in an MP4 container, the standard format for iTunes and Apple devices.
