Audiophiles, audio professionals, and sound engineers must often convert audio files from FLAC to ALAC format. They do this for various reasons, like device compatibility, platform integration issues, workflow problems, etc. Irrespective of your reason for FLAC to ALAC conversion, your choice of audio file converter determines the ease of conversion and quality of output. Therefore, we've created this easy-to-follow guide to bring you the best tools and give you a quick tutorial on converting FLAC files to ALAC format.
Part 1: Understanding FLAC and ALAC File Format
1. What is FLAC?
FLAC is a lossless audio format developed by the Xiph.Org Foundation for storing audio content in its original quality. The free and open-source audio format uses advanced compression algorithms to compress audio content to reduce file size by as much as 60% in comparison to lossless, uncompressed audio formats like WAV. Its royalty-free licensing and efficient compression have made FLAC a widely used format in the audio industry.
However, FLAC is not natively supported on a number of platforms, such as Apple. Also, several audio editing tools do not handle FLAC files as well as other lossless audio formats like ALAC.

2. What is ALAC?
ALAC is a lossless audio format developed by Apple. Although the file format is open-source, its adoption is not as extensive beyond the Apple ecosystem. Like FLAC, ALAC is also a compressed lossless audio format. The file sizes of FLAC and ALAC are similar, owing to the similar quality of compression achieved by both audio formats. However, unlike FLAC, Apple lossless audio codec ALAC is natively supported across the entire Apple ecosystem. This includes devices like iPhone, Mac, iPad, etc.; services like iTunes; and tools like GarageBand, Logic Pro, etc.
Part 2: Best FLAC Converter to Change FLAC to ALAC on Mac and Windows

The FLAC to ALAC conversion is performed directly, which ensures complete quality preservation even after conversion. This makes HitPaw Univd the ideal tool for converting FLAC audio files to Apple lossless audio codec ALAC.
