2020 Top 4 Online and Desktop M4A to FLAC Converters

Author by Cooper

Update on April 14, 2020

When we need to convert M4A to FLAC, we always want to find the best converter. So today I will recommend 3 online M4A to FLAC converters, and the best desktop one: HD Video Converter Factory Pro.



FLAC is a lossless music format, while M4A is not, or not exactly. In a word, M4A is a container, which generally contains two audio encoding methods, i.e., one is AAC, and the other one is the ALAC encoding method developed by Apple. Among them, if the ALAC encoding method is adopted, M4A is a lossless music format at this time. And in contrast, if the encoding method of AAC is adopted, then M4A is a lossy music format.

So before we convert M4A to FLAC, we should know what encoding method M4A uses. If it is AAC, then it is not necessary to convert to FLAC, because after the conversion, the audio file which we get is still a lossy file. It will not improve the sound quality, and it will also cause unnecessary memory usage. I suggest you converting the lossy M4A into MP3 so as to enable the M4A played on other devices except for Apple devices.
