Converting to AIFF won't restore lost quality
Your OPUS file has already undergone lossy compression. Converting to AIFF preserves what's left — it prevents further degradation from re-saving — but it will not magically sharpen a blurry image or recover discarded audio frequencies.
Some metadata may not survive
Your OPUS file may contain Ogg tags, Vorbis comments metadata. AIFF 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 — AIFF is universally supported and will work everywhere.
