With this SoConvert tool, you can convert multiple EAC3 files to OPUS directly in your browser for free. You can also adjust the audio Bitrate during conversion.
Click the Options button in the top-right corner to open the settings panel, where you can customize the output OPUS audio Bitrate.
Other Settings Explained:
Encoding Speed: Choose the encoding speed. Faster speeds result in larger file sizes.
Audio Bitrate: Recommended range is 8 – 320 Kbps.

About EAC3 files
E-AC3 (Enhanced AC-3) is an advanced audio codec developed by Dolby, extending the capabilities of standard AC3. It supports higher bitrates, more audio channels (up to 7.1), and improved compression efficiency while maintaining backward compatibility. E-AC3 is commonly used in Blu-rays, streaming services, and digital broadcasts for immersive surround sound. Though still a lossy format, it offers better audio quality than AC3, particularly for complex soundscapes, making it a preferred choice for high-fidelity home theater systems.
About OPUS files
Opus is a versatile, open-source audio codec developed by the IETF, combining the strengths of both speech and music compression. It delivers high-quality sound at very low bitrates, making it ideal for VoIP, streaming, and real-time communication. Opus excels in dynamic bitrate adjustment and works well across a wide range of applications, from low-latency gaming chats to high-fidelity music streaming. Supported by most modern browsers, devices, and platforms, it has become a key format for internet audio.
