Why convert WMA to OPUS?

  • Compress years of dictation and voice-recorder WMA files into a fraction of their size with clarity intact.
  • Share old recordings through modern voice-first platforms — Opus is the codec Discord and WhatsApp already speak.
  • Stream archives from self-hosted servers where Opus minimizes bandwidth per listener.

Tip: Voice-recorder WMA is usually mono speech — 32 kbps Opus preserves it fully while cutting storage by three-quarters or more.
