One-Click Convert FLAC to iTunes for Windows or Apple Music for Mac[Apple Lossless, AIFF, WAV, M4A, AAC]

People who want to listen to the best quality music with iTunes or Apple Music concerns much about the lossless conversion between audios. One of the most common questions is how to convert FLAC (Free Lossless Audio Codec) to iTunes in M4A (ALAC or Apple Lossless).

In this post, I’d like to share my experience of how I convert FLAC to iTunes on Windows and Apple Music on Mac. It’s 100% free on Mac. And, you want to convert FLAC to MP4, WAV, AIFF, no problem. You will have the all-in-one solution too.

More About the Audio Files iTunes and Apple Music Support

What Audio formats does iTunes support? When you go for Preference settings in iTunes on Windows, and then General-Import Settings, you will see the supported encoders by iTunes are: AAC, AIFF, Apple Lossless, MP3, and WAV. And, this is true for the Apple Music app for later macOS like Catalina and Big Sur. You can also check the supported formats in the Music app Preference-File-Import Settings.

Among those audio files, WAV and AIFF are uncompressed, and both come with a large bit rate. For example, AIFF is always 1411 kbps. In this way, WAV and AIFF can maintain the original quality of your CD. However, they can be huge. One more thing that needs your attention is that tags and metadata are not well supported by WAV and AIFF. You may lose that information when you transfer them from one device to another. 

For AAC and MP3, they are lossy and your music will be compressed. So the file size is reasonably smaller but you can hear the loss of your music in quality.

Apple Lossless, the Apple Lossless Audio Codec, as the name suggests, is lossless and can retain the full quality of your CD or FLAC music. Importantly, it can be 50% smaller than WAV and AIFF.
