Convert Opus audio into the OGG Vorbis format used by many open-source players and games. The conversion runs locally in your browser with no upload.
In “Local” mode your file never leaves your device. No uploads, no server – ideal for sensitive recordings.
Pick “Local” for full privacy or “Server” for very large files and every format.
No sign-up, no queue, no watermark. Choose a file, convert, download.
No. Opus and OGG Vorbis are both lossy, so this is a transcode with possible minor quality loss. A sufficient bitrate keeps it small.
Some programs, game engines and older tools expect OGG Vorbis rather than Opus. Converting ensures compatibility in those environments.
At equal quality, OGG is usually a little larger than Opus, since Opus is more modern and efficient. The difference depends on the chosen bitrate.
Yes. By default the conversion runs entirely in your browser. An optional server mode is there only for very large files.
