| Sound quality | Encoded at 128 kbps, which most people can’t tell from the original |
|---|---|
| Tags and cover art | Title, artist, album and cover carried over where OPUS holds them; lyrics and some rarer tags aren’t yet |
| File size | Usually smaller: OPUS compresses more tightly than FLAC |
When to use OPUS: Voice calls, voice notes and streaming, where low delay and small size matter.

No. The file is read and converted by your own browser, and nothing is sent to a server. You can check: open your browser’s developer tools, go to Network, and convert a file. No upload appears.
OPUS is a compressed format, and Anyfile saves at high quality, so the difference is very hard to notice. For no loss at all, keep the FLAC.
Yes. Drop them together and you get one ZIP with every OPUS inside.
