About OGG and FLAC
OGG Vorbis .ogg
An open container, normally holding Vorbis audio. Created specifically to avoid the patent licensing that surrounded MP3.
Good for
- Open and royalty-free
- Better quality than MP3 at the same bitrate
- Standard in games and open-source software
Trade-offs
- Lossy
- Patchy support on consumer hardware
- Largely superseded by Opus for new work
audio/ogg
FLAC .flac
Lossless compression for audio. Roughly half the size of WAV, and it decodes back to the original samples exactly — nothing is approximated.
Good for
- Perfect reconstruction — identical to the source
- Around 50–60% of the size of WAV
- Full tagging, and an open royalty-free format
Trade-offs
- Still far larger than MP3 or AAC
- Not supported by every portable player or car stereo

What changes when you convert OGG to FLAC
This is a re-encode, not a repackage
Some tools can move a stream into a different container untouched when the codecs happen to line up. We do not — every job here is decoded and encoded again, so the conversion takes time in proportion to the length of the file and costs a small amount of quality even where a repackage would have been possible. In exchange the output is predictable: it plays everywhere, rather than inheriting whatever the source happened to contain.
What your FLAC will contain
The output is FLAC — which is lossless, so there is no bitrate to set — the size is decided entirely by how compressible your audio turns out to be, usually landing near half of the equivalent WAV while preserving every sample exactly.
Quality cannot come back
OGG already discarded detail permanently, and FLAC stores exactly what it is given. The result will be considerably larger while sounding identical to the OGG you started from — lossless preserves, it does not restore. That is still the right move if you are about to edit, because further saves will not degrade it again.
