Is this WMV to WAV converter really free?

Yes. Up to 5 files at a time, no signup, no catch. The free tier adds a small watermark to image output — Pro ($9.99/mo or $49/yr) removes it, raises the file size limit to 500 MB, and unlocks unlimited batch conversion.

Are my files uploaded to a server?

No — and you can verify it yourself. Open DevTools → Network tab, then convert a file. You'll see zero upload requests. Everything runs right in your browser. We never see your files.

How long does conversion take?

Usually 1–3 seconds for a typical file. The very first conversion on a fresh page load may take 5–20 seconds while the converter engine loads — after that it's instant. Your CPU does all the work locally.

What is the file size limit?

Free: up to 10 MB per file, 5 files per batch. Pro: up to 500 MB per file, unlimited batch. If you're working with large videos or RAW photos, Pro is built for that.

Can I batch convert multiple WMV files at once?

Yes — drop multiple files at once (or Ctrl/Cmd+click to select them) and they all convert in parallel. Free accounts handle up to 5 files per batch; Pro has no limit.

What bitrate will the converted audio use?

We default to 192 kbps for MP3, 128 kbps for OGG/Opus, and 320 kbps for M4A/AAC. These settings are perceptually transparent — most listeners can't tell the difference in a blind test.

Will my metadata (ID3 tags, album art) be preserved?

Yes, when both formats support it. Tags carry over on conversions like MP3→M4A or FLAC→MP3. WAV has limited tag support, so some metadata may not transfer.

Is WAV extracted from WMV uncompressed?

Yes — the WMA audio inside the WMV is decoded and stored as uncompressed PCM WAV. The WAV contains every decoded audio sample, making it suitable for professional audio editing.

Will quality be lost decoding from WMA to WAV?

The WMA compression that already existed in the source cannot be undone. The WAV stores the decoded samples losslessly, but original audio detail lost by WMA compression is not recovered.

How private is this converter?

Completely private — by design, not policy. There is no upload endpoint. Files are processed right inside your browser tab and disappear the moment you close it. We collect only anonymous page-view counts; your file content is never seen or stored.

Why convert WMV to WAV?

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.

Quality & file size: WMV to WAV

Typical file sizes: WMV 50–150 MB → WAV 30–50 MB.

Both WMV and WAV use lossy compression. We transcode at high quality settings (equivalent to WAV's recommended web quality) to minimize generational loss.

Color depth: WMV supports standard color, WAV supports standard color.

Transparency: WMV does not support transparency. WAV does not support transparency — transparent areas become solid white.
