FAQ

Are my audio files uploaded?

No. The WAV file is decoded and encoded in your browser.

Why start with WAV to MP3 only?

WAV to MP3 is a stable lightweight first step. A wider audio converter would need a larger ffmpeg.wasm package.

Which bitrate should I choose?

128 kbps is a good default for speech. Use 192 or 256 kbps when music quality matters more than file size.
