FAQ
common questions
Why convert OPUS to MP3?
OPUS is the most efficient lossy audio codec available — matching MP3 320 kbps quality at just 128 kbps — but it's not universally supported. Discord, WebRTC, and modern podcasts use Opus internally, but iTunes / iOS music libraries, older car stereos, many Bluetooth speakers, and most DJ software don't accept Opus files. MP3 plays everywhere.
Will I lose quality?
Some — both formats are lossy, so the converter does a generational lossy step (decode Opus, re-encode MP3). Opus is more efficient than MP3 per bit, so converting a 96 kbps Opus to a 96 kbps MP3 actually sounds noticeably worse — you'd need a higher MP3 bitrate (160 or 192 kbps) to match the Opus quality. At 192 kbps MP3 the conversion is transparent for most listening.
How does file size compare?
MP3 is bigger at matched quality. Opus's headline feature is efficiency — a 64 kbps Opus often sounds as good as a 128 kbps MP3. Converting will roughly double the file size to maintain comparable quality. For voice content (podcasts, Discord recordings), this matters less — a 30-min recording goes from ~15 MB Opus to ~30 MB MP3.
Where do Opus files typically come from?
Discord audio exports (Discord uses Opus internally), modern voice recordings, WebM video soundtracks (often Opus), and an increasing number of podcasts. WhatsApp voice messages are Opus too, though they typically export as M4A on Apple platforms. The format is well-loved by audio engineers but consumer support has lagged.
Will the conversion preserve tags?
Limited — Opus uses Vorbis comments for metadata, MP3 uses ID3. The converter translates between them; basic tags (title, artist, album) transfer. Many Opus files don't have rich tags to begin with (they come from voice apps that don't add them), so the MP3 may come out untagged. You can add tags afterward in any music app.
