When to Convert
Common scenarios where this conversion is useful
Extract audio from Windows Media Player recordings
WMV was the default video format for Windows Media Player. Extract audio from old Windows-recorded videos, screen captures, or corporate presentations as WAV for editing or archiving.
Pull training or presentation audio from WMV
Corporate training videos and PowerPoint-exported presentations often save as WMV. Extract the audio track as WAV for use in podcast editing, voice-over extraction, or transcription workflows.
Recover audio from old Windows camcorder footage
Many older Windows-based camcorders and webcams recorded video in WMV format. Extract the audio as WAV to preserve it losslessly before the original file degrades or becomes unplayable.
Get audio from a WMV screen recording
Windows screen recording tools like Game Bar and older Windows tools often save in WMV. Extract the narration or system audio as WAV for use in video editing or voice-over projects.

Frequently Asked Questions
WAV is uncompressed. WMV typically contains WMA or MP3 audio, both of which are lossy. Converting to WAV preserves exactly what's in the WMV without adding further compression — but won't recover quality lost in the original encoding.
No. WAV is a pure audio format. ChangeThisFile extracts only the audio track from your WMV video — the video stream is discarded.
ChangeThisFile uses FFmpeg, which supports all common WMV audio codecs including WMA (Windows Media Audio), MP3, and PCM. All will be extracted and converted to WAV correctly.
Most WMV files convert in under 30 seconds. WMV files are generally compact, so conversion is typically fast regardless of video length.
Yes. Your file is uploaded over an encrypted HTTPS connection and is automatically deleted from our servers immediately after conversion. We do not store, share, or analyze your files.
WAV is uncompressed, making it ideal for audio editing, professional workflows, and archiving. MP3 re-encodes the audio with additional lossy compression. Use WAV when you plan to edit or process the audio.
No. ChangeThisFile processes WMV files entirely on our servers using FFmpeg. No Windows Media Player, Microsoft codecs, or local software is required.
ChangeThisFile cannot process DRM-protected WMV files. If your WMV was purchased from a digital store and has copy protection, conversion will fail. Only unprotected WMV files can be converted.
If the WMV file contains no audio stream, the conversion will fail or produce an empty file. Video-only WMV files cannot produce a WAV output.
