About Converting FLAC to OGG
FLAC compresses audio losslessly, cutting file size roughly in half versus WAV while preserving every bit of the original. It is the audiophile standard for archiving music. When you need to move away from FLAC, the usual reason is simple: larger than lossy formats.
Converting your FLAC audio file to OGG solves that. OGG (Vorbis) is a free, open lossy audio format that rivals AAC in quality. It is popular in gaming and open-source software but less common on consumer devices. In practice you gain free and open, no patents and good quality at low bitrates. PrivConvert runs the whole FLAC-to-OGG conversion in server memory and deletes your file the instant the OGG is ready — nothing is stored, logged or reused.
When this conversion helps
- You need free and open, no patents
- You need good quality at low bitrates
- Sharing a FLAC audio file with someone whose software expects OGG
Tips for best results
- OGG uses lossy compression, so keep your original FLAC if you may need to re-edit later — each lossy re-save loses a little quality.
- Files up to 250 MB are supported, and you can batch-convert several FLAC files at once; each is processed privately and deleted immediately.
