WAV to MP3 Without Quality Loss

Converting WAV to MP3 involves lossy compression. Some data will be discarded. Use a high bitrate to keep loss minimal and nearly inaudible.

WAV (.wav) · Max 20 MB

WAV stores audio without any compression artifacts. MP3 uses perceptual coding to reduce file size. The encoder discards audio data it predicts you won't hear.

At 320kbps, most listeners can't distinguish MP3 from the lossless source in blind tests. Use the highest bitrate your use case allows.

AudioUtils lets you pick the output bitrate. Choose 320kbps for near-transparent quality. Choose 128kbps for smaller files when size matters more than fidelity.

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.
