Why convert WAV to MP3?

WAV files are uncompressed PCM and can be 10× larger than MP3. Conversion is essential for email, web, and mobile distribution.

What bitrate is right for voice recordings?

128 kbps mono is perfectly fine for spoken audio. Music benefits from 192–256 kbps.

Is my recording uploaded?

No. ffmpeg.wasm runs locally — your WAV never reaches a server.
