How to convert AC3 to WAV

  1. Drop your .ac3 files above, or click Upload Files. You can add many files at once.
  2. WAV is already selected as the output. Open the settings (gear icon) to fine-tune the result.

  4. Download your .wav files as soon as each one finishes.

What to know about AC3 to WAV conversion

  • Converting a lossy AC3 to WAV cannot restore detail that was already discarded, but it avoids any further loss in later edits.
  • You can choose the bitrate, sample rate and channels (mono, stereo or a 3D spatial effect).

Frequently asked questions

Is it safe to convert AC3 to WAV here?

Yes. Your files are processed entirely on your own device by WebAssembly code running in the browser. They are never uploaded, so nobody else can see them, and the converter keeps working even if your connection drops after the page loads.

Is there a file size limit?

There is no server-side limit. The only limit is the memory available to your browser, typically 1.5–4 GB on desktop computers.

Can I convert several AC3 files at once?

Yes. Add as many files as you like; they are converted in parallel according to your device's CPU cores, and you can apply the same settings to all of them.
