Choose eligible FLAC files
Add non-empty .flac files up to 100 MB each. Conversion requires an audio stream that host FFmpeg can decode.
Server-backed FLAC to OGG conversion
Encode FLAC audio as Vorbis OGG files.
Add supported FLAC tracks and Fileverses will make audio-only OGG downloads from the first audio stream of each successfully processed source.
- Vorbis quality 5
- Audio-only output
- 100 MB per file

Supported files
FLAC source, Vorbis OGG result.
FLACOGG
This route decodes a supported FLAC source and makes a new OGG file for workflows that request OGG audio. It is a re-encode rather than a remux.
How it works
Queue FLAC, then collect new OGG audio files.
Convert with the fixed profile
Run the queue to encode the first audio stream as a new Vorbis OGG at the route's fixed quality setting 5.
Download each OGG result
Review a completed file in compatible software and download it individually; failed sources remain identifiable in the queue.
Encoding boundaries
Fixed Vorbis settings and first-stream mapping.
The FFmpeg profile maps only the first audio stream, removes source metadata and chapters, omits video, and creates Vorbis at quality setting 5. It has no custom encoding controls.
Convert FLAC to OGGFLAC files up to 100 MB
This page accepts only non-empty .flac uploads no larger than 100 MB. Files that FFmpeg cannot read or that contain no audio cannot be converted.
Vorbis, not copied FLAC audio
Each result is a new OGG container with libvorbis quality setting 5. The source codec is not copied, and output size can be either larger or smaller depending on the source.
First audio stream only
Only the first audio stream is mapped. Video, alternate audio tracks, subtitles, and attachments are not included in the audio-only OGG result.
No source tags or editing tools
Source metadata and chapters are removed. There are no controls for trimming, streams, bitrate, channel layout, sample rate, or Vorbis quality.
FLAC-to-OGG details
Know the output before download
What does Fileverses produce from a FLAC file?+−
A successful conversion produces an audio-only OGG file encoded with Vorbis at quality setting 5 from the source's first audio stream.
Is FLAC to OGG a lossless conversion?+−
No. FLAC is decoded and then re-encoded as Vorbis OGG, which is lossy. The route does not promise identical audio, recovered detail, or a particular final size.
What FLAC uploads are allowed?+−
Use non-empty .flac files no larger than 100 MB. The host FFmpeg installation must be able to read an audio stream in the source.
Will the OGG keep metadata and chapters?+−
No. The profile removes source metadata and chapters before creating the output, so the downloaded OGG should be treated as a new file.
Can I choose the Vorbis quality or audio bitrate?+−
No. This route uses a fixed libvorbis quality setting of 5 and does not expose bitrate, sample-rate, channel, stream-selection, or trimming controls.
Can I submit a batch of FLAC tracks?+−
Yes. Add multiple eligible tracks. The client sends queue items one by one and each server-side conversion is handled sequentially, producing separate downloads.
Does a visible source preview prove conversion will work?+−
No. Browser preview support and FFmpeg readability are separate checks. A source needs to be readable by host FFmpeg for conversion, and playback also depends on browser support.
