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.
