Convert OGG to FLAC
Updated Jul 2026
OGG (Ogg Vorbis) is a compressed audio format popular with games and open media projects, and FLAC is a lossless format that preserves the full audio quality of a source file. To convert OGG to FLAC, open the file in a converter and export it as FLAC. Doing this on your own computer means the audio file never has to leave your machine.

- Choose FLAC as the output format.
- Convert. The FLAC file is written locally next to your original, and nothing leaves your machine.
OGG vs FLAC: what actually changes
| OGG | FLAC | |
|---|---|---|
| File size | Smaller, a compressed format | Larger, often several times the size |
| Quality | Lossy, some detail discarded when encoded | Lossless, keeps every bit of the source it was made from |
| Compatibility | Common in games and open media, not universal | Widely supported by music players and audio software |
| Metadata | Basic tags supported | Full tag support, including cover art |
| Recovers lost detail | N/A | No, converting doesn't add back what OGG already discarded |
When to convert, and when not to
Convert OGG to FLAC when you want a format with broader support in music software, or when you're archiving audio alongside other lossless files and want everything in one consistent format.
Keep the OGG if it came from a game or app that needs that exact format to work, since converting won't improve the audio and just gives you a much larger file with the same underlying quality.
Why not just use an online converter?
Audio files like game soundtracks or personal recordings often aren't meant for a stranger's server, but that's exactly where an online converter sends them while it works. Converting OGG to FLAC on your own computer keeps the file local the whole time, no upload, no account, no waiting on someone else's server.
Questions
Does converting OGG to FLAC improve the sound quality?
No. OGG is lossy, so whatever detail was discarded when the file was originally encoded is gone for good. FLAC will store the OGG's quality exactly as it is, in a larger, lossless file, but it can't recreate what was already lost.
Why convert to FLAC if it won't sound better?
Mainly for compatibility and consistency. FLAC works with more music software and hardware than OGG, and it's a common choice if you're keeping a library where everything else is already lossless.
Will the FLAC file keep my track titles and cover art?
Yes, FLAC supports the same kind of metadata tags as OGG, so titles, artist names, and artwork carry over in the conversion.
Can I convert OGG to FLAC without uploading the file anywhere?
Yes. A desktop app like Morphjet converts the file on your own computer, so it never travels over the internet. You can do it with your wifi off.
Is the resulting FLAC file much bigger than the OGG?
Usually, yes. FLAC stores the full waveform rather than compressing it away, so a FLAC file is typically several times larger than the OGG it came from.
