02 / what you get
What happens to your data
Kept
- Opus files from WhatsApp, Discord and other apps are supported
- Saved as FLAC, which keeps the audio exactly as decoded, in a file usually about half the size of WAV
- Sample rate, channels and 24-bit depth are kept
- Title, artist and album tags are carried over
Good to know
- Embedded cover art is not carried over. Only the sound is converted.
- The source is already compressed with quality loss. FLAC keeps it exactly as it is, it does not bring back what was lost, and the file gets much bigger.

OPUS vs FLAC
OPUS
An OPUS file uses one of the most efficient audio codecs available today — smaller files than MP3 at equal quality, especially good for voice. It's what WhatsApp voice messages and Discord calls use under the hood.
Used in: Voice messages (WhatsApp) · Discord & voice calls · Modern streaming
FLAC
A FLAC file compresses audio without losing any quality (lossless) — smaller than WAV, but still identical to the original when played back. The go-to format for audiophiles and music archiving.
Used in: Music archiving · Audiophile listening · High-quality downloads
