WAV (.wav) · Max 20 MB

The converter defaults to the highest practical bitrate for MP3. For lossy output, that means 320kbps or VBR quality 0. Transparent quality for virtually all listeners.

Garbage in, garbage out. The output quality depends on your source. A 128kbps WAV file won't sound better in MP3. Start with the best source available.

AudioUtils processes everything locally using WebAssembly. The encoder runs at near-native speed. A 10-minute file converts in seconds with maximum quality settings.

Frequently Asked Questions

How much smaller will my MP3 be compared to WAV?

About 10x smaller. A 50MB WAV file converts to roughly 5MB as MP3 at 320kbps. At 128kbps, it's even smaller — around 2MB.

What bitrate should I use?

320kbps for the best quality, 192kbps for a good balance of quality and size, 128kbps for voice recordings or podcasts where size matters more than fidelity.

Will I lose audio quality?

Yes, MP3 is a lossy format. But at 320kbps, the difference from WAV is nearly imperceptible to most listeners. For casual listening and sharing, it's more than enough.

Are my files uploaded to a server?

No. Conversion happens entirely in your browser. Your audio files never leave your device.
