How do I convert LU to MP3?

Upload your LU file, choose bitrate (e.g., 320 kbps), click 'Convert', and download the resulting MP3. The process usually takes less than a minute.

Why convert LU to MP3 instead of keeping LU?

MP3 is a universal audio format compatible with all devices, media players, and editors, whereas LU files often require specialized software. Converting also reduces file size, making it easier to share and store.

Will converting LU to MP3 degrade audio quality?

MP3 is a lossy format, so it discards some audio data during compression. Our converter uses a high bitrate (up to 320 kbps) to minimize audible loss. Frequency response and sample rate are preserved as closely as possible, but you may notice slight differences on high-end audio equipment.
