Generation loss — quality may degrade
M4A uses lossy compression, and so does AVI. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your M4A file may contain MP4 atoms, iTunes tags metadata. AVI has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.

Your device saves files in M4A by default (Apple Music, iTunes downloads). Most people convert because the files won't open on other devices — AVI is universally supported and will work everywhere.

AVI lossy compression can produce codec-dependent. At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
