Some metadata may not survive
Your OPUS file may contain Ogg tags, Vorbis comments metadata. WAV has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Default format on Discord
Your device saves files in OPUS by default (Discord, WebRTC calls, WhatsApp calls). Most people convert because the files won't open on other devices — WAV is universally supported and will work everywhere.
