Is my WAV uploaded to a server?

No. Conversion runs entirely in your browser with WebCodecs and a local MP3 encoder. Nothing is sent to us.

What bitrate do you use?

Default is 192 kbps stereo. You can pick 64, 96, 128, 192, or 320 kbps before you convert.

Up to 80 MB or 30 minutes, whichever comes first. Longer files need a desktop editor.

If it has an audio track, we export that audio as MP3 and ignore the video.

Turn a WAV into a smaller MP3 you can send or post. Runs in your browser. Your file never leaves this device.

Choose a WAV file (any audio file or video with an audio track also works)
Pick a quality (default High, 192 kbps); set an exact bitrate under Advanced settings
Click Convert and wait for encoding to finish
Preview the result, then download your MP3
