What is Opus?
Opus is a modern open codec that beats MP3 and AAC at low bitrates, which is why it powers most voice chat and is excellent for speech and music alike.
What is FLAC?
FLAC is lossless but compressed, giving bit-perfect audio at roughly half the size of WAV — the audiophile and archival choice.
Why convert Opus to FLAC?
Most people convert Opus to FLAC for compatibility — a website, app or device insists on FLAC, and Opus simply won't open. FLAC is widely supported, which makes it a dependable target. Audio is processed with ffmpeg using high-quality encoders (LAME, libopus, libvorbis, FLAC and more), so you get the best possible result for the destination format.
Opus vs FLAC: what changes
Going from the lossy Opus to the lossless FLAC won't recover detail Opus already discarded, but it gives you a clean, re-editable copy that won't degrade further when you edit and re-save it.
