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.

How to convert Opus to MP3 with Movavi Video Converter

To convert your files quickly and easily, try using Movavi Video Converter. The software lets you convert videos, audio files, and images, and also provides editing and compression options, prepares files for use on Apple and Android devices, and much more. Just download the converter for Windows or Mac and read the guide below to learn how to convert Opus to MP3.

Step 1. Install the Opus-to-MP3 converter

Download the installation file for the Opus-to-MP3 converter for PC or Mac and install it following the on-screen instructions. After the installation is complete, the program will open automatically.

Step 2. Add files to the program

Click the Add Media button, and then select Add Audio. Choose the files you want to convert and click Open. The program supports batch processing, so you can add multiple files at once. This advantage is exclusive to the desktop converter; the online Opus-to-MP3 converter doesn’t work with batches.

Step 3. Select the output format

Open the Audio tab in the lower part of the program window. Click MP3 and select a preset with the appropriate bitrate. Remember that the higher the bitrate and the quality of the file, the more space it will take.

Converted files are saved to the Movavi Library folder by default. If you want to change the destination folder, click the Save to button in the bottom-right part of the program window and specify a different folder. To change the format of the Opus file to MP3, click the Convert button.
