Deep Dive
MP3 vs ALAC: What Changes When You Convert

ALAC is stored in an M4A container (.m4a extension). All Apple devices recognize it natively.

Frequently Asked Questions
Does converting MP3 to ALAC improve audio quality?
No. MP3 is a lossy format and any audio data discarded during the original encoding is gone permanently. Converting to ALAC cannot recover that data. What you gain is a lossless container that prevents any further quality loss in subsequent edits or re-exports.
What file extension does the converted ALAC file use?
ALAC is stored inside an M4A container, so the output file has a .m4a extension. This is correct and expected. All Apple devices and most modern media players including VLC and foobar2000 recognize it.
Why is the converted ALAC file larger than the original MP3?
ALAC stores every decoded audio sample without discarding data, so lossless files are always larger than the lossy source. A typical 10 MB MP3 can become 50 to 80 MB as ALAC. This is expected behavior.
Which devices and apps support ALAC playback?
All Apple devices natively support ALAC: iPhone, iPad, Mac, Apple TV, and HomePod. On other platforms, VLC, foobar2000, Winamp, and most modern Android media players also support it.
Is there a file size limit?
The upload limit is 100 MB per file. Most typical MP3 tracks are well within this limit.
