How to convert Opus to OGG
Add your Opus files
Drag and drop Opus files into the box or tap to choose them. The converter engine (about 31 MB) downloads once, the first time you convert.
Pick a bitrate
192 kbps suits music and 128 kbps or less suits speech. Sample rate and mono/stereo are under Advanced.
Convert and download
Click Convert, then download each OGG file or all of them as one ZIP.
Why convert Opus to OGG?
Some older players and game engines support Vorbis but not Opus.
What happens when you convert Opus to OGG?
The audio is re-encoded to Vorbis at 192 kbps.
How does Fylo convert Opus to OGG?
Fylo decodes the Opus audio in the Opus with ffmpeg compiled to WebAssembly and encodes it with the Vorbis encoder (libvorbis) at 192 kbps in an Ogg container. Both formats are lossy, so each conversion discards a little detail — start from the highest-bitrate Opus you have. A 3-minute song is ≈ 2.9 MB at 128 kbps as Opus and ≈ 3.6 MB at 160 kbps as OGG. The original sample rate and channel layout are kept unless you change them under Advanced.
What's the difference between Opus and OGG?
Opus is an open, royalty-free codec standardised by the IETF as RFC 6716 in 2012. It blends speech technology from Skype's SILK with music coding from Xiph's CELT, so it handles both voice and music well. Files are usually stored in the Ogg container with the .opus extension.
Ogg is an open container from the Xiph.Org Foundation; Vorbis, the audio codec most .ogg files use, reached version 1.0 in 2002. Vorbis was created as a free, unpatented alternative to MP3 and sounds better at the same bitrate.

Frequently asked questions
Aren't both Ogg?
Yes, but the codecs differ — some older software only decodes Vorbis.
Will quality change?
Slightly.
Is my Opus file uploaded to a server?
No. Fylo runs ffmpeg, the same engine used by professional video tools, compiled to WebAssembly inside your browser. Your Opus file is read directly from your device and never sent anywhere.
