Generation loss — quality may degrade
MP3 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 MP3 file may contain ID3v1, ID3v2 metadata. WMV has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
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.
