AAC uses lossy compression, and so does WMV. 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 AAC file may contain MP4 atoms, iTunes tags metadata. WMV 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 devices (iTunes, Apple Music)
Your device saves files in AAC by default (Apple devices (iTunes, Apple Music)). Most people convert because the files won't open on other devices — WMV is universally supported and will work everywhere.
What compression artifacts to expect
WMV lossy compression can produce blockiness, smearing. 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.
