How to convert .opus to .mp3

Ben Jacklin Edited by Ben Jacklin

What is Opus? It’s an open audio codec and file format designed to transmit voice notes and music over the Internet. Opus is mainly used by music streaming services, video conferencing apps, and messengers, such as WhatsApp and Telegram. It offers a low lag in transmitting data while maintaining a high quality of sound.

However, since the format is relatively new, it’s not supported by all applications and devices. So, if you have a problem opening a file with the .opus extension, one of the best solutions is to turn the file into a more popular format, for example, MP3.

What is the Opus file format?

Opus is a lossy audio coding format that allows the coding of general audio and speech into a single format. Its short latency makes it ideal for recording telephony, voice over IP, and videoconferencing.

To convert Opus to MP3, you can use the Opus-to-MP3 converter online above or a desktop version described below. Read the article and choose the option that suits you best.
