How do I convert an OPUS file to LU?

Upload your OPUS file by tapping 'Select File', choose LU as the output format, and optionally adjust sample rate or channel settings. Click 'Convert', then download the resulting LU file. All processing is done in your browser—no installation required.

Why should I convert OPUS to LU?

OPUS is a lossy codec that reduces file size by discarding some audio detail. LU is a lossless format that maintains the full original quality, making it ideal for professional editing, mastering, and archival. Many DAWs also lack OPUS support but accept LU natively, saving compatibility headaches.

What technical data is preserved during OPUS to LU conversion?

The converter decodes OPUS PCM audio and re-encodes it into LU without any lossy steps. Sample rate, bit depth, channel configuration, and duration are kept exactly as the original. Metadata such as title, artist, and album art is also copied. Note that LU files may be larger than the source OPUS because lossless PCM encoding prioritizes fidelity over size.
