About Free Lossless Audio Codec
Common Use Cases
- Wrapping OGG audio in a widely-supported lossless container
- Archiving decoded Vorbis audio for long-term storage
- Player compatibility for devices that support FLAC but not OGG
OGG Vorbis is a solid open-source lossy codec, but FLAC has broader player and device support. Media servers, portable hi-fi players, and many car stereos support FLAC but not OGG Vorbis. Converting OGG to FLAC decodes the lossy audio and stores it in a lossless container, giving you the widest possible compatibility. The conversion does not improve audio quality since the Vorbis encoding already discarded data.
OGG Vorbis is a lossy codec that discards audio data for compression, while FLAC is a lossless container that preserves every sample. Converting OGG to FLAC stores the decoded lossy audio losslessly, preventing further degradation.
Why Convert OGG to FLAC?
Broader device support
FLAC is supported by virtually every music player, portable device, car stereo, and media server. OGG Vorbis support, while decent, is missing from some hardware and Apple devices.
Media server first-class support
Plex, Jellyfin, and Roon treat FLAC as a primary format with native playback. OGG Vorbis may trigger unnecessary transcoding on some servers.
No further quality loss
Once in FLAC, the audio can be copied, moved, and converted to other formats without any additional degradation from this point forward.
Archival format standardization
If you are archiving a mixed-format library, FLAC is the standard lossless target. Converting OGG to FLAC lets you standardize even your lossy content in one container format.

How to use
- Upload your OGG file. Drag and drop an .ogg file onto the upload area, or click to browse from your device. Files up to 500 MB are supported.
- Start the conversion. Click Convert File. Your OGG Vorbis audio is decoded and re-encoded as FLAC on our servers using FFmpeg.
- Download your FLAC. Once processing finishes, click the download link to save your FLAC. Both the uploaded OGG and converted output are deleted from our servers within 1 hour.
Frequently asked questions
- Does converting OGG to FLAC improve quality?
- No. OGG Vorbis is lossy, so audio data was already discarded. FLAC preserves the decoded audio losslessly but cannot recover what Vorbis already removed.
- Why convert lossy OGG to lossless FLAC?
- Player compatibility and archival. FLAC is supported by more devices and media servers than OGG Vorbis. The lossless container also prevents further quality loss in future conversions.
- Will the FLAC be larger?
- Yes, significantly. Lossless FLAC encoding is inherently less space-efficient than lossy Vorbis. The decoded audio takes more space when stored without lossy compression.
- Will metadata transfer?
- Yes. FFmpeg maps OGG Vorbis comment fields to FLAC Vorbis comments. The metadata format is actually the same, so tags transfer cleanly.
- Is converting OGG to FLAC free?
- Yes. Anyone can convert for free with no signup. Anonymous users have a daily cap, registered accounts get higher limits, and Premium or Lifetime members get unlimited conversions.
- Does FLAC play on Apple devices?
- Yes. iOS supports FLAC since iOS 11, and macOS supports it in Apple Music. Most modern Apple devices handle FLAC without issues.
- Is there a file size limit?
- Yes. The maximum upload size is 500 MB.
