AAC to WAV Converter
Fixpio’s aac to wav converter decodes an AAC audio file and hands it back as an uncompressed WAV — and it does the whole job inside your browser. Add your file, convert it, and download a 16-bit PCM WAV that audio editors, DAWs and video projects open without fuss. Because nothing is sent to a server, your recording stays on your device the entire time.

Works with AAC audio your browser can decode. An M4A file containing AAC is a good choice — it usually decodes more reliably than a raw .aac file, especially in Chrome. See the FAQ below if a file will not convert.
None to adjust — the output is a standard 16-bit PCM WAV, ready to edit.
Why convert AAC audio to WAV
Three practical reasons an uncompressed copy is easier to work with.
Ready for your DAW
A clip pulled from a screen recording, a voice recorder or a phone often arrives as AAC. As a WAV it imports cleanly into audio editors and DAWs, sits on a timeline without codec surprises, and behaves like any other production audio.
Edit without losing more
AAC already discarded some audio to stay small. Working from a WAV from this point on means your edits, effects and re-exports do not squeeze it a second time — the sound you start with is preserved through the project.
Private from start to finish
Most converters ask you to hand your file to a server. This one never asks: the audio is decoded and converted on your own machine, then handed straight back to you.
About this converter
People usually convert aac to wav at the moment a compressed clip needs to become working audio: a voice note that has to sit in a podcast edit, AAC audio from a screen recording going into a video project, or a track a DAW refuses to import directly. This page is built for exactly that moment. It is a free aac to wav converter that runs online in your browser, so there is no program to install and no account to create before you can start.
The aac vs wav difference is simple. AAC is a lossy format — the same family of audio used by YouTube, Apple devices, streaming services and broadcasts — designed to sound good in a small file. WAV stores the decoded audio uncompressed, which is why the result is much larger and why editors prefer it. Converting does not add back anything AAC removed; it gives you that same audio as an uncompressed wav you can edit, process and archive without further loss.
Frequently asked questions
Straight answers about quality, file size, formats and privacy.
How do I convert an AAC file to WAV on this page?
Add your file using the upload box — drag it in or browse for it — then press Convert to WAV. Your browser decodes the AAC audio, writes it as a 16-bit PCM WAV and offers it as a download. The whole process takes three short steps and never involves a server.
Will converting AAC to WAV make my audio sound better?
No — and any converter that promises otherwise is not being straight with you. AAC is a lossy format: some audio was removed when the file was first compressed, and no conversion can bring it back. What you get is the same audio, stored uncompressed. That is still worth having, because editors and DAWs work with WAV directly and your edits will not be compressed a second time on export.
Why is the WAV file so much bigger than my AAC file?
That is normal and expected. AAC keeps files small by discarding audio data; WAV keeps everything it is given, uncompressed — roughly 10 MB per minute of stereo audio at standard settings. The larger size is the trade for a file that editing and production tools can work with sample by sample. If you only need the WAV for one project, you can delete it afterwards and keep the smaller AAC as your listening copy.
What is the difference between AAC and M4A? Can I use an M4A file here?
AAC is the audio format itself — the way the sound is compressed. M4A is a container: an Apple-style file that usually holds AAC audio along with details like a title or artwork. In practice, most M4A files are AAC audio in a wrapper, and yes, you can use one here. In fact, an M4A file often converts more reliably than a raw .aac file, because browsers find the container easier to decode.
My .aac file will not convert. What is wrong?
Most likely, the file is a raw AAC stream. Raw .aac files often fail to decode in Chrome because they lack the container information the browser expects, and this converter can only decode audio your browser can decode. Two things usually help: try the same audio as an M4A file if you have it, or try a different browser — M4A files containing AAC usually decode well in Chrome, Edge and Safari. If a file still fails, the page will tell you plainly rather than produce a silent or broken WAV.
Are my audio files uploaded anywhere? Is this converter free?
No to the first, yes to the second. Fixpio’s converter runs entirely in your web browser, on your own device. Your file is not sent anywhere, not stored by us and not heard by anyone else — when you close the tab, nothing of your recording remains with us, because it never left your machine in the first place. Converting costs nothing, and there is no account, sign-up or software installation involved.
