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.
