How it works

Three steps, all in your browser

01

Drop your M4A

Drag in the .m4a — a voice memo, an interview, a rehearsal take. The AAC audio inside is decoded on your own device.

02

Convert in your browser

The decoded audio is written into a 16-bit WAV at the source sample rate. Nothing is uploaded to a server.

03

Download the WAV

A Download button hands you the WAV, ready to drop into Audacity, a DAW, or any editor that prefers uncompressed audio.

Why convert M4A to WAV

Get a recording ready to edit

Voice memos and phone recordings land as .m4a, but a lot of editing and transcription tools want plain WAV. Converting gives you an uncompressed file those tools open without complaint — handy before cutting an interview, cleaning up dialogue, or feeding audio into another app. Built for recordings up to 30 minutes or 500 MB.

FAQ

Frequently asked questions

How do I convert an M4A to WAV?
Drop your M4A onto the converter. The AAC audio inside is decoded and written out as a 16-bit WAV right in your browser, then a Download button appears. No install, no account, no upload.
Does this work with iPhone voice memos?
Yes. iPhone Voice Memos and most recording apps export .m4a files containing AAC audio. Drop one in and you get a WAV that audio editors and DAWs open directly.
Is my file uploaded?
No — conversion happens entirely in your browser. Your file never leaves your device.
Will converting M4A to WAV improve the recording?
No — M4A/AAC is lossy, and WAV cannot restore detail it already discarded. The point of converting is to get an uncompressed file your editor accepts, not to add quality.
How long a recording can I convert?
The converter is built for recordings up to 30 minutes or 500 MB, which covers voice memos, interviews, and rehearsal takes.
