FLAC (Free Lossless Audio Codec) and ALAC (Apple Lossless Audio Codec) are both popular lossless audio formats that offer CD-quality sound and good compression. However, FLAC is not compatible with Apple Music/iTunes. So you may need to convert FLAC to ALAC to sync your lossless music collection via Apple software or devices. This article will show you 4 simple ways to convert FLAC to ALAC in seconds, no complex tools or technical skills required.
*Before we dive into the tutorial, please note that M4A is the file container for ALAC codec compression, so converting FLAC to ALAC will produce a .m4a file.

Tips:
XLD stands for X Lossless Decoder, a tool for Mac OS designed to transcode lossless audio files. It supports FLAC, Apple Lossless (ALAC), APE, AIFF, WAV and lossy formats such as AAC and MP3. It lets you preserve the FLAC metadata or edit it yourself. It’s quite easy to use but it doesn’t have a graphical user interface, which can be confusing at first.
Step 1. Get XLD from Sourceforge and run it. XLD is unverified by Apple, so to open it, you need to find it in the Finder, then right-click on it and select “Open”. And XLD won’t display a window, but will show in the Dock at the bottom of your screen.
Step 2. Go to XLD > Settings to set it up. Choose “Apple Lossless” from the “Output format” drop-down list, and specify a directory to save the output files.
Step 3. Open your FLAC audio files with XLD to convert them to ALAC. There are three ways to do it:

Step 4. In the new window, select “Apple Lossless” as the output format, and click Convert.
Step 5. Select a save folder when prompted, then it will start converting FLAC to ALAC one by one.

Step 1. Go to converter.app/flac-to-alac/ using any web browser.

What’s the difference between FLAC, ALAC and other lossless music formats? And which one is the best choice? Well, there are four most common lossless audio formats, FLAC & ALAC and WAV & AIFF. They offer equal sound quality but differ in their compression ratio and compatibility.
FLAC is both an audio codec and a container, and ALAC is like the Apple version of FLAC but stored within an M4A container. Their file sizes are very close, with ALAC being 5~10% larger than FLAC.
WAV and AIFF are lossless and uncompressed audio formats that are typically 60%~ larger than FLAC & ALAC. WAV is commonly used on PCs and is also compatible with Apple software, while AIFF is developed by Apple and works mostly on Macs.
Therefore, if you manage your music library in iTunes/Apple Music, ALAC is the first choice that saves storage and offers studio quality.
No, they are both lossless formats so the output audio quality is the same as the source file. And converting FLAC to a lossy format like AAC and MP3 will certainly lose quality.
No. If you right-click on a FLAC audio file and choose “Encode Selected Audio Files” on your Mac, you can only get an error code-2700 as FLAC is not supported by Apple. But you can still convert ALAC to AAC, iTunes Plus or other supported formats with it.
FFmpeg is a cross-platform command-line tool designed for converting video and audio files. It’s not included above because it’s too complex for this task and require a steep learning curve. Although I managed to convert some FLAC files to ALAC using FFmpeg, some files with tag information failed.
