Why OGG to FLAC does not create lossless audio

The two codecs

Ogg Vorbis is a lossy format from the Xiph.Org Foundation. FLAC, from the same family, is lossless. They share a heritage and a tagging system, which is why people expect a move between them to be an upgrade.

What you really get

A FLAC made from an OGG holds the already-compressed sound perfectly, with no more loss. It is not a hi-fi version of the song. The packaging changes, the audio does not.

When it is useful

A player that only reads FLAC, a library tool that rejects OGG, or an editing workflow where you want to avoid a second lossy encode are all valid reasons to convert.

Space cost

The FLAC will be several times the size of the OGG. A 128 kbps OGG is about 1 MB a minute, while the FLAC is often 5 to 6 MB a minute.

Keep your claims honest

Anyone who shares the file should not call it lossless or high-resolution. Collectors check spectrograms, and files built from lossy sources stand out immediately.

Have the original CD or purchase? Make FLAC from that, then create OGG copies for games or portable use.

Frequently asked questions

Does converting OGG to FLAC improve the sound?+

No. Ogg Vorbis is lossy, and the detail it discarded is gone. FLAC keeps what is left perfectly, so the sound is unchanged.

Why would I convert OGG to FLAC?+

Some players, libraries and workflows only accept FLAC. Others convert so that later edits do not add another lossy encode. These are practical reasons, not quality ones.

How big will the FLAC be?+

Much bigger than the OGG. A 128 kbps OGG is about 1 MB a minute, while the FLAC of the same audio is often 5 to 6 MB a minute.

Is the result true lossless?+

It is a lossless container for lossy audio. Do not label it as a genuine lossless or high-resolution copy if you share it, because spectrograms reveal the source.

Would WAV be a better choice?+

If the goal is editing, yes, because WAV is accepted by more software. FLAC is better for storage and tags, since it is smaller and carries metadata. Use the OGG to WAV page if you need WAV.

Do tags carry over?+

Titles and artists often do, since Ogg Vorbis and FLAC use similar tag systems. Cover art may not, so check one file first.

Is there a file size limit?+

Yes. Files larger than 50 MB are not accepted, and the FLAC you download will be several times larger than the OGG.
