Convert WAV to M4A

No. The conversion runs entirely in your browser. The file never leaves your device – there is no server that could see it. Once the page has loaded, the tool even works offline.

WAV is uncompressed audio – perfect quality, very large files. M4A is AAC audio in an MP4 container – the format of Apple Music and iTunes.

M4A is a lossy format. At 192 kbit/s the difference to the original is inaudible for almost everyone; choose 320 kbit/s if in doubt. Converting one lossy format into another loses a little more each time, so keep the original.

Text tags (title, artist, album, year) are carried over where the target format supports them – all formats except WAV do. Embedded cover art is dropped.

Audio is quick: a three-minute song converts in a few seconds once the engine (about 32 MB, loaded once per visit) is ready. Files up to 100 MB are accepted.
