How do I convert LU files to OPUS online?

Upload your LU file, select OPUS as the output format, choose your preferred bitrate or quality preset (e.g., 128 kbps for transparent output), then click 'Convert'. Download the resulting OPUS file instantly. The whole process runs server-side, so no software installation is needed.

Why should I convert LU to OPUS instead of keeping the original?

OPUS is a modern lossy audio codec that offers superior compression efficiency compared to older formats like MP3. It is widely supported across browsers, mobile devices, and smart speakers. Converting LU to OPUS reduces file size dramatically while retaining near-lossless audio quality, making it perfect for streaming, archiving with limited space, or sharing over email.

Will converting LU to OPUS affect audio quality or metadata?

The conversion decodes the LU stream and re-encodes it in OPUS. Bitrate and sample rate are preserved according to your settings; OPUS supports up to 48kHz and 256 kbps per channel. Any embedded album art or tags may be retained or converted, but lossy encoding discards inaudible sound data. For archival purposes, we recommend keeping an original LU copy and using OPUS for distribution.
