WAV (.wav) · Max 20 MB
The MP3 encoder in AudioUtils is based on well-tested open-source libraries. It supports CBR and VBR modes with configurable bitrate and quality targets.
Most online converters use server-side FFmpeg with default settings. AudioUtils gives you control over output parameters while keeping the process local and private.
WAV is lossless. Converting to MP3 reduces file size at the cost of some audio data. Use a high bitrate to minimize loss. For critical work, always A/B test the output against your source to confirm the result meets your standards.
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.
