Convert M4A to WAV
Turn an iPhone voice memo or any .m4a (AAC) recording into a WAV you can edit. Drop the file in and the audio is decoded and written out as a 16-bit WAV right in your browser. It is free, there is no sign-up, and your file is never uploaded.
Free, no sign-up. Converted in your browser — your file is never uploaded.
Three steps, all in your browser
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.
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.
Download the WAV
A Download button hands you the WAV, ready to drop into Audacity, a DAW, or any editor that prefers uncompressed audio.
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.
