Frequently asked questions
What MP3 quality do I get?
Constant 320 kbps — the highest MP3 bitrate supported, close to CD quality while a fraction of the WAV size.
Is my WAV uploaded to a server?
Conversion happens in your browser with WebAssembly — your file never leaves your device, so nothing is uploaded or stored.
How large a WAV can I convert?
Up to 500 MB per file. Larger files may take longer but still run fully on your machine.
Why convert WAV to MP3?
WAV is uncompressed (roughly 10 MB per minute of stereo audio). MP3 shrinks it by about 10× while remaining compatible with virtually every player.
