Generation loss — quality may degrade
M4A uses lossy compression, and so does WMA. 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. WMA has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
Default format on Apple Music
Your device saves files in M4A by default (Apple Music, iTunes downloads). Most people convert because the files won't open on other devices — WMA is universally supported and will work everywhere.
What compression artifacts to expect
WMA lossy compression can produce smearing, loss of high-frequency detail. 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.
