Convert RMVB to ALAC — Free Online Converter

Apple Lossless Audio Codec (ALAC) compresses audio without any data loss, typically achieving 40-60% size reduction compared to PCM. RMVB files store audio using RealNetworks' proprietary codecs at bitrates usually between 64-128 kbps. Converting RMVB to ALAC extracts the audio and wraps the decoded signal in Apple's lossless container. While the source audio is already lossy, ALAC ensures no further degradation through the conversion pipeline.

ALAC integrates natively with Apple's ecosystem — iTunes, Apple Music, iPhone, iPad, HomePod, and Apple TV all handle ALAC without transcoding. For users managing audio libraries on Apple devices, ALAC is the preferred lossless format. Extracting RMVB audio to ALAC creates Apple-native files ready for immediate library import.
