Quikbench
Turn M4A recordings — voice memos, GarageBand exports, iTunes downloads — into uncompressed WAV right in your browser tab.
Drop in one or more M4A files. Each is decoded and re-encoded as standard PCM WAV, ready for editors, DAWs, or transcription tools that expect WAV.
Every tool on Quikbench follows the same rule: your files are read, converted, and turned into a download entirely inside this browser tab — nothing is ever uploaded to a server.
Converts M4A (AAC) files to WAV entirely locally in your browser. Your M4A file is decoded to raw audio and re-encoded as a standard 16-bit PCM WAV file — nothing is sent to a server.
Convert one file at a time, or queue several M4A files and convert them all to WAV in a single batch, with a zip download when you're done.
Every WAV file this tool produces is a real, standard PCM WAV — playable anywhere, editable in any audio software, with no server round trip.
M4A files — common from iPhone voice memos, GarageBand, and Apple Music downloads — aren’t always accepted by editing software, DAWs, or transcription tools that expect uncompressed audio. Converting to WAV gives you a universally compatible file ready for further work.
This is a straightforward format conversion — it doesn't trim, normalize volume, or edit the audio in any way. If you need to cut a clip or adjust levels, do that in a dedicated audio editor before converting here. Need other formats too? The full Audio Converter handles MP3, WAV, M4A, MP4, AAC, OGG, and FLAC in one place.
Drop your M4A file into the box above, wait a moment while it's read in your browser, then hit Convert and download the WAV file. No account or install needed.
No. The whole conversion, from reading the M4A file to producing the WAV download, happens locally in your browser tab using the Web Audio API. Nothing is sent to a server.
Yes, there's no cost, no account, and no watermark. Since conversion happens on your device, there are no server-side usage limits either.
It depends on the direction. Converting a lossy format (like MP3, MP4/AAC audio) to WAV doesn't recover any quality that was already lost — it just repackages the same audio uncompressed. Converting to MP3 applies lossy compression, so some quality is deliberately traded for a smaller file.
Yes — queue up to 20 files (300MB combined) and convert them all in a single batch, then download everything as one zip file.
Any modern browser with Web Audio API support — Chrome, Edge, Firefox, and Safari all work. If a specific file fails to decode, try a different browser, since audio/video codec support varies slightly between them.
