About ASF to ALAC Conversion
ALAC (Apple Lossless Audio Codec) compresses PCM audio to roughly 50-60% of its original size without any quality loss. ASF files carrying WMA or WMA Lossless audio can be converted to ALAC, giving you bit-perfect decoded audio in a format natively supported by every Apple device — iPhone, iPad, Mac, Apple TV, and HomePod.
Why Convert ASF to ALAC?
ALAC is the only lossless codec natively supported across the entire Apple ecosystem without third-party apps. If you have ASF audio files and use Apple devices, ALAC provides the best combination of quality preservation and storage efficiency. Unlike AIFF or WAV, ALAC compresses losslessly, saving 40-50% of disk space while sounding identical to the uncompressed source.

- Building a lossless Apple Music library from Windows Media audio archives
