| 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 | About the same |
When to use OPUS: Voice calls, voice notes and streaming, where low delay and small size matter.

About OPUS filesEverything that converts to OPUS
Need to change it first? Open the audio editor
Drop your 3GA file on this page, or choose it. Anyfile converts it on your device in a moment and the OPUS downloads straight away. To change it first, open it in the audio editor.
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.
Yes. Drop them together and you get one ZIP with every OPUS inside.
