WAV (.wav) · Max 20 MB
Most free converters add watermarks or throttle quality. AudioUtils does neither. You get the same output quality whether free or paid.
Free users get 5 conversions per day. That covers most casual needs. The conversion engine is identical to Pro. Same speed, same quality, same privacy.
Your files stay on your machine. Nothing is uploaded. WAV is lossless. Converting to MP3 reduces file size at the cost of some audio data. Use a high bitrate to minimize loss.
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.
