What happens to your data
Kept
- Opus files from WhatsApp, Discord and other apps are supported
- Saved as a raw AAC (ADTS) stream at 192 kbps
Good to know
- A raw .aac file has no room for title, artist or album tags. Choose M4A if you want the tags kept.
- Some players show a slightly wrong length for raw AAC files and cannot jump around in them as smoothly as in M4A.
- Embedded cover art is not carried over. Only the sound is converted.
- Both formats compress with quality loss, so every conversion costs a little quality. Keep your OPUS original.

OPUS vs AAC
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
AAC
An AAC file is a compressed audio format similar to MP3 but with better sound quality at the same bitrate. It's the standard for streaming audio, YouTube, and most modern devices' default recordings.
Used in: Streaming audio · YouTube · Modern device recordings
