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.

About Lossless Audio Formats

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.


Frequently Asked Questions

Is there quality loss when converting from FLAC to ALAC?

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.

Can I convert FLAC to ALAC with Mac built-in feature?

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.

How to convert FLAC to ALAC using FFmpeg?

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.

  1. Install FFmpeg.
  2. Open the Command Prompt (on Windows) or Terminal (on Mac), and drag the FFmpeg tool to the interface. This way you don’t need to remember the directory.
  3. Tell FFmpeg where to find the FLAC file and convert it to ALAC with the -acodec option: ffmpeg -i input.flac -acodec alac output.m4affmpeg convert FLAC to ALAC
  4. Press Enter, and it will start the conversion process.
