Free M4A to WAV Converter

Turn M4A files, such as voice memos and recordings from a phone, into uncompressed WAV files that every audio and video editor opens. Your files are converted in your browser and never leave your device.

Online M4A to WAV Converter

M4A is the format Apple devices use for voice memos and music: AAC audio inside an MP4 container. WAV stores audio uncompressed, which is what editing software works with best.

When to Convert M4A to WAV

Convert to WAV when you want to edit a recording: cut an interview, clean up a voice memo, use it in a video project or load it into a sampler. Some editors do not open M4A at all, and a WAV can be saved as often as you like without being compressed again. If you only need a file that plays everywhere, the M4A to MP3 Converter gives you a much smaller one.

Will the Audio Sound Better as WAV?

No. The WAV contains exactly the audio that was in the M4A file, uncompressed, so it is several times larger and sounds the same. What you gain is a format that editing programs accept and that loses nothing more when you work on it.

16-Bit or 24-Bit?

16-bit is the CD standard and is accepted by every program and device; choose it unless you have a reason not to. 24-bit leaves more room for later processing in an editing program, at one and a half times the file size. Neither adds detail that the source file did not have.

Convert Several Files at Once

You can add up to 20 files in one go. They are converted one after another on your device, and each one gets its own download button; Download All saves them all. The sample rate and the channels of each file are kept: nothing is resampled, and mono stays mono.

Frequently Asked Questions

Is the M4A to WAV Converter really free?

Yes. It is free to use, with no sign-up, no daily limits and no watermark on your files.

Are my audio files safe and private?

Yes. The audio is processed in your browser on your own device. Your files are never uploaded to our servers.

How do I convert an iPhone voice memo to WAV?

Save or share the voice memo to the Files app or to your computer, open this page and choose the .m4a file. Pick 16-bit, click Convert to WAV and download the result.

What is an M4A file?

An M4A file is an MP4 container that holds only audio, usually compressed with AAC. Apple devices use it for voice memos, GarageBand exports and music.

Does converting M4A to WAV improve the quality?

No. The audio stays exactly as good as the M4A file was. The WAV is larger and easier for editing software to handle, but detail that was lost when the M4A was made is not restored.

Why does my M4A file not open?

Two kinds of M4A files cannot always be converted here: songs with copy protection (old iTunes purchases, usually ending in .m4p) and, in some browsers, files in the Apple Lossless (ALAC) format. Ordinary voice memos and AAC music files open in all modern browsers.

Should I choose 16-bit or 24-bit WAV?

16-bit works everywhere and is the right choice in most cases. Choose 24-bit if the file is going into a project that uses 24-bit audio. The source file does not gain detail either way.

Can I convert several files at once?

Yes. Add up to 20 files, click Convert to WAV and download each result, or use Download All.

Is there a file size limit?

There is no fixed limit. The conversion runs on your own device, so very long files need a lot of memory; if a long file fails on a phone, try it on a computer.

Do I need to install any software?

No. The tool runs in your web browser on computers, phones and tablets.
