About Ogg Vorbis Audio
Common Use Cases
- Creating streaming-friendly versions of lossless archives
- Preparing game audio from high-quality masters
- Distributing music for open-source and Linux platforms
FLAC preserves every sample of your audio losslessly, which is perfect for archiving but impractical for streaming, game distribution, and bandwidth-constrained delivery. OGG Vorbis compresses audio efficiently with excellent quality at typical streaming and gaming bitrates, and because you are encoding from a lossless FLAC source, the Vorbis output will be the best quality the format can achieve. OGG also has the advantage of being completely royalty-free, making it the preferred choice for game developers, open-source projects, and anyone distributing audio commercially.
FLAC preserves every bit of audio losslessly at the cost of large files, while OGG Vorbis uses efficient lossy compression to produce compact files ideal for streaming, games, and distribution.
Why Convert FLAC to OGG?
Best possible OGG quality
Encoding from FLAC gives you the highest quality OGG Vorbis output because the source is lossless. Unlike converting from MP3 or AAC, there is no prior lossy compression degrading the audio before Vorbis gets to it.
Streaming-friendly file sizes
A 40 MB FLAC song becomes roughly 3 to 5 MB as OGG Vorbis, making it practical for music streaming services, internet radio, web players, and mobile apps where bandwidth and storage are constrained.
Royalty-free for commercial use
OGG Vorbis has no patent licensing history to worry about. Game studios, app developers, and content creators can distribute OGG audio commercially without royalty concerns.
Excellent for game and web audio
Game engines like Unity and Godot recommend OGG for compressed audio assets. Web browsers support OGG through the HTML5 audio element. Converting your FLAC masters to OGG creates distribution-ready assets for both platforms.

How to use
- Upload your FLAC file. Drag and drop a FLAC file onto the upload area above, or click to browse your computer. Uploads are capped at 500 MB per file.
- Start the conversion. Click the Convert File button. Your FLAC is decoded and encoded to OGG Vorbis on our servers using FFmpeg with the libvorbis encoder.
- Download your OGG file. Once encoding finishes, a download link appears. Save the OGG wherever you need it. Both your upload and the output are automatically deleted from our servers within 1 hour.
Frequently asked questions
- Is converting FLAC to OGG free?
- Yes. Anyone can convert for free with no signup. Anonymous users get a daily conversion allowance, free registered accounts get a higher cap, and Premium or Lifetime members enjoy unlimited conversions.
- How much smaller will the OGG be?
- Expect roughly a 5 to 10x reduction. A 30 MB FLAC song typically becomes 3 to 5 MB as OGG. A full 300 MB FLAC album usually lands between 30 and 60 MB.
- Is OGG Vorbis better than MP3?
- At the same bitrate, yes. Vorbis consistently sounds better than MP3, especially at lower bitrates. It is also royalty-free, which is why game developers and open-source projects prefer it.
- Will the conversion preserve my hi-res FLAC quality?
- OGG Vorbis is lossy, so any hi-res detail (24-bit depth, 96 kHz sample rates) is reduced during encoding. The result still sounds excellent because it is encoded from lossless source material, but it is not bit-perfect.
- How long are my files kept on your servers?
- Both your uploaded FLAC and the converted OGG are automatically deleted within 1 hour. All transfers are encrypted and files are never shared with third parties.
