Turn your M4A file into a WAV that plays where you need it, right in your browser.
Drag and drop the file, or click to browse. Files up to 500 MB are supported, and nothing is installed.
WAV is already selected. Switch between MP3 and WAV if you change your mind.
We convert on our servers, usually in under a minute. Create a free account to download the WAV, or keep editing the file in REQO.
M4A is AAC audio in an MP4 container: what an iPhone Voice Memo, GarageBand export or Apple Music download hands you. It sounds better than MP3 at the same bitrate, but the extension confuses older hardware and plenty of upload forms.
The practical problem: Older car stereos, media players and some upload forms reject .m4a. ALAC-encoded M4A files are far larger than people expect.
WAV solves that. Lossless, so repeated edits and exports never compound compression artefacts. The format audio editors, DAWs and mastering tools expect.
| M4A | WAV | |
|---|---|---|
| Container | MPEG-4 audio | RIFF / WAVE |
| Typical codecs | AAC (lossy) or ALAC (lossless) | Uncompressed PCM |
| Best for | Voice memos and Apple audio exports | Editing, mastering, voiceover work |
| Plays on | Apple devices natively, most others too | Every desktop and audio tool; large for phones |
| File size | Slightly smaller than MP3 at the same quality | About 10 MB per minute in stereo |
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 WAV itself beyond the free-plan badge.
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.
Converting to WAV adds no further loss, but it cannot restore anything the M4A encoder already discarded. You get a clean, uncompressed working file, not a better-sounding one.
Up to 500 MB per file. For anything bigger, trim or compress it first, both are free tools here.
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.
