Quick FAQ
- What bitrate should I choose? `128 kbps` is a practical balance for everyday sharing, while `192 kbps` or higher is safer for music or more critical listening.
- When does mono help? Mono is useful for voice-heavy audio where stereo space does not matter and smaller files are more important.
- Will it work on GitHub Pages? Yes. The conversion runs in the browser and the MP3 encoder is stored locally with the site.
