Why convert FLAC to Opus?
FLAC — A perfect-quality copy of the original. Great for music libraries you want to keep for years.
Opus — The best small-size sound. Used for podcasts, voice chat, and the web.
FLAC keeps the song exactly as it was recorded. Opus makes a much smaller file by leaving out parts of the sound most people can't hear. At the standard quality setting, the difference is hard to notice for most listeners on most devices.
All of this happens right inside your web browser. Your file stays on your phone or computer the whole time.
