Convert OGG to FLAC online
Use this OGG to FLAC converter to turn OGG files into FLAC right in your browser — ideal for lossless music, audiophile libraries and archiving audio. OGG uses lossy compression and FLAC uses lossless compression, so file size and quality can change.
When should you convert OGG to FLAC?
- When you need it for lossless music
- When you need it for audiophile libraries
- To open your files in apps that prefer FLAC
- To share FLAC files more easily
What happens to your file
The OGG audio is decoded and re-encoded to FLAC with FLAC at lossless compression. There is no video stream involved, so the job is quick even for long recordings.

What changes
- FLAC is lossless, but it can only preserve what is already in the OGG file. Detail removed when the OGG was first encoded does not come back — you get a bigger file of the same audio, not a better one.
- Cover art, lyrics, and most tags are not carried across — the output keeps the audio, not the metadata around it.
