Convert M4A to WAV
M4A is compressed for size; WAV is uncompressed, which is what audio editors, DAWs and transcription pipelines often want to work from. This decodes an M4A to a WAV file with WebCodecs in your browser, so the audio is never uploaded and there is no cap on size or count.
Runs entirely in your browser — your file is never uploaded.

Frequently asked questions
Why convert to WAV?
WAV is uncompressed PCM, so it is the clean, editable master that editing software and mastering tools expect. It is a larger file, but there is no further quality loss the way there is when re-encoding to another compressed format.
Is the file uploaded?
No. The conversion runs with WebCodecs on your device, so the audio never leaves the browser — no account, no quota, no size limit. Chrome, Edge and Firefox work best.
