The most efficient codec for voice and music at small sizes. It is what WhatsApp and video calls use.
How do I open a OPUS file?
You can open it right here to convert it into something more convenient. If your computer does not recognise it, the practical move is to convert it to a universal format such as PDF.
What is the maximum OPUS size here?
300 MB. Since conversion happens inside your browser, the limit comes from your device memory, not from a server.
Are my OPUS files uploaded to a server?
No. All processing happens on your own device, so the file never leaves it.
