Converting M4A / AAC audio to WAV

Morphr decodes your M4A / AAC and writes it as WAV with no further loss. A lossless target keeps exactly what’s there, though it can’t restore quality a previously-compressed file already gave up.

M4A / AAC and WAV, explained

M4A (AAC) is the lossy audio format used by Apple Music and iTunes, generally better than MP3 at the same bitrate. WAV is uncompressed PCM audio — the raw, lossless studio format. Files are large but hold the exact waveform.

Good to know

• • Your M4A / AAC files never leave your device — everything converts locally in the browser, so even confidential ones stay private.
• • Convert as many M4A / AAC files as you like at once; a batch comes back as a single ZIP.
• • No sign-up, no watermark and no size limit beyond your device’s memory.

The private way to turn M4A / AAC into WAV

With Morphr, the whole conversion runs inside your browser tab using Morphr's own engine, so your file is never uploaded to a server, queued, or stored. That makes it a safe choice for personal photos, scanned documents and anything you'd rather not hand to a third party.
