What to know about WAV to AAC conversion
- AAC is lossy, so files become much smaller than the WAV source. 192 kbps or higher is transparent for most listeners.
- You can choose the bitrate, sample rate and channels (mono, stereo or a 3D spatial effect).

Frequently asked questions
Is it safe to convert WAV to AAC 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 WAV 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.
