MP3 audio to Vorbis OGG
Re-encode MP3 audio as a new Vorbis OGG file.
Add eligible MP3 files to the server queue and download audio-only OGG results made from each first audio stream.

Supported files
MP3 in. Vorbis OGG out.
MP3OGG
Fileverses decodes the first MP3 audio stream and writes a new OGG using the fixed Vorbis quality-5 profile.
How it works
Queue MP3 files and collect new Vorbis OGGs
Run the conversion queue
Fileverses submits one item at a time to its fixed FFmpeg Vorbis profile.
Keep each OGG
Listen where the browser supports it, then download every separately named OGG result.
Encoding details
A second lossy encode with fixed settings.
The output is Vorbis quality 5, not copied MP3 data. It cannot restore earlier losses, and result size varies with the source.
Convert MP3 to OGGEligible MP3 input
Only non-empty .mp3 files up to 100 MB are accepted, and host FFmpeg must be able to read an audio stream.
First audio stream only
The route maps the first audio stream; it does not expose alternate-track selection.
Fixed Vorbis quality 5
A new audio-only OGG is encoded with libvorbis at quality setting 5. This is not a stream copy.
No recovery or editing
Video, source metadata, and chapters are removed. Re-encoding cannot recover MP3 losses, and no trim or audio controls are available.
MP3 to OGG FAQ
Vorbis output, plainly stated
Which codec is used for MP3 to OGG output?+−
The fixed profile encodes the first audio stream with libvorbis at quality setting 5 in an audio-only OGG file.
Is this a lossless conversion?+−
No. MP3 is already lossy, and the route performs another lossy encode; it cannot restore discarded source detail.
Can the OGG have a predictable size?+−
No. Output size depends on the source and fixed encoder, so no smaller or fixed result size is promised.
Can I convert multiple files?+−
Yes. Eligible MP3 uploads are processed sequentially, with a separate download for every completed result.
What MP3 files are supported?+−
The route accepts non-empty .mp3 files up to 100 MB that host FFmpeg can read and that contain audio.
Are metadata and chapters kept?+−
No. The conversion removes source metadata and chapters and keeps only the first mapped audio stream.
Can I choose the bitrate or trim the audio?+−
No. This route uses a fixed quality-5 Vorbis profile and has no editing, bitrate, channel, or sample-rate controls.
