Converting to WAV won't restore lost quality
Your WMA 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 WMA 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 WMA to WAV Conversion
WMA (introduced 1999) and WAV (introduced 1991) are both audio formats, but they differ in important ways. WMA (Windows Media Audio) is Microsoft's audio codec — less common today but still found in legacy collections. WAV is uncompressed PCM audio — studio quality with no data loss, but large file sizes.
Full Name: WMA uses Windows Media Audio, while WAV uses Waveform Audio. Compression: WMA uses Lossy, while WAV uses None (uncompressed). Typical File Size: WMA uses 1 MB per minute at 128 kbps, while WAV uses 10 MB per minute at 44.1 kHz/16-bit stereo.

What Happens When You Convert WMA to WAV
Your WMA audio is decoded into raw PCM samples, then re-encoded as WAV. No audio quality is lost in this conversion.
Your WMA file is decoded — compressed audio becomes raw PCM waveform data
The raw audio is re-encoded using Waveform Audio's none codec
Metadata (tags, artwork, track info) is transferred where WAV supports it
The WAV file is saved and ready for download

Should You Convert WMA to WAV?
When to Convert

- ✓A website, service, or platform only accepts WAV uploads

Common Mistakes When Converting WMA to WAV
"Converting WMA to WAV will improve the quality"
No. WMA 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 WMA file"
WAV uses no compression, so the output file is often larger than a lossy WMA. If you need a small file, WAV may not be the right choice.
