Opus (Opus Interactive Audio Codec) uses lossy compressed encoding and is best for voice-over-IP, real-time communication, and streaming at very low bitrates with excellent quality. MP3 (MPEG-1 Audio Layer 3) uses lossy compressed encoding and excels at universal music playback and sharing across all devices and platforms. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
