# Convert Opus to OGG

Convert Opus to OGG right in your browser — free, private, nothing is uploaded. One-click re-encode for compatibility.

Opus delivers the best quality per bit of any mainstream codec — it beats MP3, Vorbis and AAC at almost every bitrate and powers WhatsApp voice notes, Discord and WebRTC. Device support, though, is still patchy outside browsers and messengers.

OGG (Vorbis) is a free, open lossy format with very good quality per byte — a favourite in games, open-source software and projects that want to avoid patent-encumbered codecs.

Converting Opus to OGG is a compatibility move: both formats are lossy, so the goal isn't quality — it's producing a file that fits games, open-source pipelines and the web. Expect the sound to stay essentially the same, with a small second round of encoding loss.
