About the AAC to WAV Converter
This AAC to WAV converter turns audio files from AAC into WAV without installing software or uploading anything. It solves a common problem: raw AAC streams carry no tags and some players reject them. Converting to WAV gives you uncompressed WAV for editing, ideal for audio editing, studio work, broadcast, transcription tools and sound effects.
Audio and video are processed by FFmpeg compiled to WebAssembly, the same open-source engine behind VLC and HandBrake, running inside your browser tab. Because everything happens on your own device, your audio files are never uploaded, stored or seen by anyone else, which makes it safe for voice recordings, interviews and unreleased music.
What to expect: the sample rate and channels are kept, and you can pick the bitrate; converting lossy AAC to WAV stops further loss but cannot restore detail that was removed earlier; the processing engine (about 30 MB) is downloaded once and then cached by your browser.
How to use the AAC to WAV Converter
- Click "Choose files" or drag your AAC audio files onto the box. You can add several at once.
- Choose mono or stereo; WAV is saved as uncompressed 16-bit PCM.
- Press "Convert to WAV". The conversion runs on your device and shows its progress.
- Download each WAV file, or use "Download all (ZIP)" when you converted several.
- Open the result in Audacity or Adobe Audition to check it; your original AAC is never changed.
Tips & benchmarks
- WAV is uncompressed 16-bit PCM, so it is large but loses nothing further and edits cleanly.
- Converting a compressed AAC to WAV will not bring back detail that was already discarded; it simply prevents further loss when you edit.
- As a guide, one minute of audio at 128 kbps is about 1 MB, and at 320 kbps about 2.4 MB.
- Keep the file name simple (letters, numbers and hyphens) if you plan to upload the WAV to a website or government portal.

What is a WAV file?
WAV is Microsoft and IBM's uncompressed audio format from 1991. It stores raw PCM samples, about 10 MB per minute at CD quality, so it is the safest format for editing, mastering and broadcast.
