Generation loss — quality may degrade
MKV 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 MKV file may contain Matroska tags, chapter markers, attachments metadata. WMA 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
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.
