Converting to WAV won't restore lost quality
Your WMV file has already undergone lossy compression. Converting to WAV preserves what's left — it prevents further degradation from re-saving — but it will not magically sharpen a blurry image or recover discarded audio frequencies.
Some metadata may not survive
Your WMV file may contain ASF metadata, DRM tags metadata. WAV has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
About WMV to WAV Conversion

Now for the details. WMV (Windows Media Video) is Microsoft's proprietary format, common in older Windows ecosystems. WAV is uncompressed PCM audio — studio quality with no data loss, but large file sizes. Converting between these two formats lets you improve file compatibility across devices.
Full Name: WMV uses Windows Media Video, while WAV uses Waveform Audio. Compression: WMV uses Lossy, while WAV uses None (uncompressed). Color Depth: WMV uses 8-bit, while WAV uses —.
Your WMV file is decoded and re-encoded as WAV. Converting WMV to WAV maintains high quality with CocoConvert's optimised encoder settings.
Common misconception: ""Converting WMV to WAV will improve the quality"" — in reality, no. wmv has already permanently discarded data during compression. converting to wav preserves what's left but cannot restore lost detail. the file will just be larger.

What Happens When You Convert WMV to WAV
The audio track is extracted from your WMV video file and saved as WAV. The video frames are discarded.
Your WMV file is opened and the container is parsed to identify audio and video streams
The audio stream is extracted — if it's already in the target codec, it's copied directly (no quality loss)
If transcoding is needed, the audio is decoded and re-encoded as WAV
Video frames, subtitles, and chapter markers are discarded
The WAV file is saved with preserved metadata (title, artist, etc.) where possible

No. WMV has already permanently discarded data during compression. Converting to WAV preserves what's left but cannot restore lost detail. The file will just be larger.
"WAV will be smaller than my WMV file"
WAV uses no compression, so the output file is often larger than a lossy WMV. If you need a small file, WAV may not be the right choice.
