WAV to M4A converter

Convert WAV audio to M4A right in your browser — no upload, no sign-up, completely free. Drop a file (or a batch) and download the M4A version in seconds. Your audio is processed on your own device and never sent to a server.

WAV is an uncompressed, lossless format that stores raw audio at full quality. Files are large, but the audio is pristine, which is why it is the standard for editing and mastering. M4A (AAC in an MP4 container) is the format Apple uses for iTunes and Apple Music. It sounds better than MP3 at the same bitrate and is widely supported on modern devices. M4A compresses the audio into a much smaller file that’s easy to share and plays everywhere, with only a small and usually inaudible loss of quality.

How to convert WAV to M4A

1. Add your WAV files. Drag your WAV audio onto the drop zone or click to browse. You can add several at once.
2. Convert. Each track is re-encoded to M4A on your device using your browser’s native audio engine.
3. Download your M4A files. Save each file, or grab them all together as a ZIP.
