How do I convert OGG Vorbis to Opus?

Upload your OGG Vorbis file using the box above, confirm Opus as the output format, then select Convert. The converted file is ready to download as soon as processing finishes — usually in a few seconds.

Is converting OGG to OPUS free?

Yes, and there is nothing to sign up for. Every conversion route is free on every plan — paying raises limits such as file size and how many conversions you get, and removes advertising. It never unlocks a format, adds a watermark or degrades the output.

Will the quality change when converting to Opus?

OPUS uses lossy compression, so some data is discarded to keep the file small. The default quality setting is tuned to be visually or audibly transparent for most material, and you can raise it in the conversion settings.

What happens to my file afterwards?

The uploaded file is deleted as soon as the conversion completes, and the converted file is removed automatically once its retention window ends. Download links are signed and expire within minutes.

About OGG and OPUS

OGG Vorbis .ogg

An open container, normally holding Vorbis audio. Created specifically to avoid the patent licensing that surrounded MP3.

Good for

Open and royalty-free
Better quality than MP3 at the same bitrate
Standard in games and open-source software

Trade-offs

Lossy
Patchy support on consumer hardware
Largely superseded by Opus for new work

audio/ogg

Opus .opus

The current state of the art in lossy audio, standardised by the IETF. It outperforms MP3 and AAC across the range and is dramatically better at low bitrates.

Good for

Best quality per byte of any format here
Excellent for speech as well as music
Open, royalty-free, and low latency

Trade-offs

Lossy
Older devices and some players will not open it
Less familiar, so people distrust the file extension

What changes when you convert OGG to OPUS

This is a re-encode, not a repackage

Some tools can move a stream into a different container untouched when the codecs happen to line up. We do not — every job here is decoded and encoded again, so the conversion takes time in proportion to the length of the file and costs a small amount of quality even where a repackage would have been possible. In exchange the output is predictable: it plays everywhere, rather than inheriting whatever the source happened to contain.

What your OPUS will contain

The output is Opus — encoded with Vorbis at 192 kbps by default. Vorbis is royalty-free and holds up slightly better than MP3 at the same bitrate, though Opus has largely superseded it for new work.

Re-encoding costs a little quality

Both formats are lossy, so this decodes OGG and compresses again as OPUS. That second pass loses a small amount on top of what was already gone. It is barely audible once, and it accumulates if a file is converted repeatedly — so convert from the original rather than from a previous conversion.
