How it works

How to convert WAV to M4A

  1. Upload your WAV file

    Drag and drop a WAV file, or click to browse. Up to 500 MB, and nothing is installed.

  2. Confirm M4A as the output

    M4A is already selected for your WAV. Switch between MP3 and WAV if you change your mind.

  3. Convert and download

    We convert the WAV on our servers, usually in under a minute. Create a free account to download the M4A, or keep editing it in REQO.

Why convert WAV to M4A?

WAV holds raw uncompressed PCM audio: nothing is thrown away, nothing is guessed on playback. It is the format audio editors and mastering tools want, and it is far too heavy to send around casually.

The practical problem: Around 10 MB per minute, so files get unmanageable quickly. Too large for email attachments or messaging apps.

M4A solves that. Better quality than MP3 at the same bitrate, and native on Apple devices.

FAQ

WAV to M4A questions

Is the WAV to M4A converter free?

Yes. Convert and preview the result for free, then create a free account to download it. There is no per-file charge and no watermark on the M4A itself beyond the free-plan badge.

Do I need to install any software?

No. The conversion runs on our servers and the whole flow happens in your browser, so it works the same on Windows, macOS, Linux, iPhone and Android. Nothing to install at either end. Where WAV plays: Every desktop and audio tool; large for phones. Where the M4A you get back plays: Apple devices natively, most others too.

Does converting WAV to M4A reduce the quality?

WAV to M4A is a re-encode, so a small amount of detail is lost. At the default quality level the difference is inaudible on speech, and for music it stays well below what typical playback gear reveals.

How large a file can I convert?

Up to 500 MB per file, which is more footage in some formats than others. WAV: About 10 MB per minute in stereo. M4A coming back: Slightly smaller than MP3 at the same quality. For anything bigger, trim or compress it first, both are free tools here.

Is my file kept private?

Your upload is processed and then held only as long as your project needs it. Nothing is published, indexed or shared unless you create a share link yourself.
