WMV to WAV Converter — Free, Online, No Upload

WMV files use Windows Media Audio (WMA) for their audio tracks — a proprietary codec that many professional audio tools refuse to decode. If you are trying to bring audio from a recorded webinar, corporate training video, or Windows-captured screen recording into a DAW or audio editor, WMV and WMA will stop you at the door.

WAV is the universal professional audio format. Every digital audio workstation — Pro Tools, Logic Pro, Ableton, Audacity, Adobe Audition — accepts WAV without question. Broadcast and post-production workflows specify WAV as the default exchange format. It is uncompressed, sample-accurate, and completely transparent to any audio tool.

Extracting the audio from a WMV file to WAV gives you a clean, uncompressed audio file that any software can immediately use. The conversion decodes the WMA audio and writes it as uncompressed PCM WAV — the quality of the output matches the quality of the WMA source. If the original WMA was recorded at low bitrate, the WAV will reflect that; no conversion recovers quality lost in the original encoding. What you gain is full compatibility with professional tools. Expect large files — WAV is uncompressed by design, with roughly 10 MB per minute for stereo 16-bit 44.1 kHz audio.

Typical sizes: WMV 50–150 MB (1 minute 720p); WAV 30–50 MB (3-minute song).

WAV output is 16-bit PCM, so a 24-bit source is reduced to 16-bit (CD quality).

WAV will not restore detail the WMV encoder removed, and the file gets bigger.
