What to know about Opus

Quality and size
Bit rate, sample rate, bit depth and compression influence both fidelity and file size.

Track titles, artists, artwork and other tags may be supported depending on the format.
Compatibility
Support for Opus varies across browsers, devices, editors and media players.
How Opus conversion works
Converting Opus decodes the source audio and encodes it with the destination format's codec and selected quality settings.
Lossy conversion cannot restore detail already removed from the source, so keep the original when quality matters.
mp3.now accepts Opus as input and can also create Opus output.
Opus compatibility and software support
Check that the target player or editing application supports Opus before choosing it for delivery.
MP3 remains a practical fallback when broad playback compatibility is the priority.
